Syntax:
=SUMIF(range, criteria, [sum_range])
Arguments:•range Required
The range of cells that you want evaluated by criteria.o Cells in each range must be numbers or names, arrays, or references that
contain numbers.o Blank and text values are ignored.

The HLOOKUP function
Microsoft® Excel® Lookup Functions
Syntax:= HLOOKUP(lookup_value,table_array,row_index_num,range_lookup)
Arguments:•lookup_value Required
The value to search in the first row of the table or range.•table_array Required
The range of cells that contains the data. •row_index_num Required
The row number in table_array from which the matching value will be returned
range_lookup Optional A logical value that specifies whether you want HLOOKUP to find
an exact match or an approximate match.
The HLOOKUP function
Microsoft® Excel® Lookup Functions
Description:• Searches for a value in the top row of a table or an array of
values, and then returns a value in the same column from a row you specify in the table or array.
Remarks:• If HLOOKUP can't find lookup_value, and range_lookup is TRUE, it uses the largest value that is less than lookup_value.
• If lookup_value is smaller than the smallest value in the first row of table_array, HLOOKUP returns the #N/A error value.
The HLOOKUP function
Microsoft® Excel® Lookup Functions
Errors:#VALUE! – If row_index_num is less than 1
#REF! – If row_index_num is greater than the number of rows in the table_array
#N/A – If range_lookup is FALSE and an exact match cannot be found
#N/A – If lookup_value is less than the smallest value in the first row of table_array
The HLOOKUP function A B C1 Axles Bearings Bolts2 4 4 93 5 7 104 6 8 11
FormulaDescription (Result)Looks up Axles in row 1, and returns the value from row 2 that's in the same column. (4)
=HLOOKUP("Axles",A1:C4,2,TRUE)
=HLOOKUP("Bearings",A1:C4,3,FALSE)
Looks up Bearings in row 1, and returns the value from row 3 that's in the same column. (7)
=HLOOKUP("B",A1:C4,3,TRUE)
Looks up B in row 1, and returns the value from row 3 that's in the same column. Because B is not an exact match, the next largest value that is less than B is used: Axles. (5)
=HLOOKUP("Bolts",A1:C4,4) Looks up Bolts in row 1, and returns the value from row 4 that's in the same column. (11)
The LOOKUP function
Microsoft® Excel® Lookup Functions
The Lookup function has two forms:
If you want to Then see Usage
Look in a one-row or one-column range (known as a vector) for a value and return a value from the same position in a second one-row or one-column range
Vector form
Use the vector form when you have a large list of values to look up or when the values may change over time.
Look in the first row or column of an array for the specified value and return a value from the same position in the last row or column of the array
Array form
Use the array form when you have a small list of values and the values remain constant over time.
Notes
The LOOKUP function – Vector Form
Microsoft® Excel® Lookup Functions
Syntax:=LOOKUP(lookup_value, lookup_vector, result_vector)
Arguments:•lookup_value Required
Value that LOOKUP searches for in the first vector. Can be a number, text, a logical value, or a name or reference
that refers to a value.•lookup_vector Required
A range that contains only one row or one column. The values can be text, numbers, or logical values.
result_vector Required A range that contains only one row or column. Must be the same size as lookup_vector.
The LOOKUP function – Vector Form
Microsoft® Excel® Lookup Functions
Remarks:•If the LOOKUP function can't find the lookup_value, the function matches the largest value in lookup_vector that is less than or equal to lookup_value. •If lookup_value is smaller than the smallest value in lookup_vector, LOOKUP returns the #N/A error value.
The LOOKUP function – Array Form
Microsoft® Excel® Lookup Functions
Syntax:
= LOOKUP(lookup_value, array)
Arguments:• lookup_value Required
Value that LOOKUP searches for in an array. Can be a number, text, a logical value, or a name or reference
that refers to a value.• array Required
A range of cells that contains text, numbers, or logical values that you want to compare with lookup_value.
The LOOKUP function – Array Form
Microsoft® Excel® Lookup Functions
Remarks:• If LOOKUP can't find the value of lookup_value, it uses the
largest value in the array that is less than or equal to lookup_value.
• If the value of lookup_value is smaller than the smallest value in the first row or column (depending on the array dimensions), LOOKUP returns the #N/A error value.
• If array covers an area that is wider than it is tall (more columns than rows), LOOKUP searches for the value of lookup_value in the first row.
• If an array is square or is taller than it is wide (more rows than columns), LOOKUP searches in the first column.
• With the HLOOKUP and VLOOKUP functions, you can index down or across, but LOOKUP always selects the last value in the row or column.
