# Selection.InsertFormula method (Word)

Inserts an = (Formula) field that contains a formula at the selection.

## Syntax

expression.Formula (Formula, NumberFormat)

expression Required. A variable that represents a Selection object.

## Parameters

Name Required/Optional Data type Description
Formula Optional Variant The mathematical formula you want the = (Formula) field to evaluate. Spreadsheet-type references to table cells are valid. For example, "=SUM(A4:C4)" specifies the first three values in the fourth row. For more information about the = (Formula) field, see Field codes:= (Formula) field.
NumberFormat Optional Variant A format for the result of the = (Formula) field. For information about the types of formats you can apply, see Numeric Picture (#) field switch.

## Remarks

The formula replaces the selection, if the selection is not collapsed.

If you are using a spreadsheet application, such as Microsoft Office Excel, embedding all or part of a worksheet in a document is often easier than using the = (Formula) field in a table.

The Formula argument is optional only if the selection is in a cell and there is at least one cell that contains a value above or to the left of the cell that contains the insertion point. If the cells above the insertion point contain values, the inserted field is {=SUM(ABOVE)}; if the cells to the left of the insertion point contain values, the inserted field is {=SUM(LEFT)}. If both the cells above the insertion point and the cells to the left of it contain values, Microsoft Word uses the following rules to determine which SUM function to insert:

• If the cell immediately above the insertion point contains a value, Word inserts {=SUM(ABOVE)}.

• If the cell immediately above the insertion point does not contain a value but the cell immediately to the left of the insertion point does, Word inserts {=SUM(LEFT)}.

• If neither cell immediately above the insertion point nor the cell immediately below it contains a value, Word inserts {=SUM(ABOVE)}.

• If you don't specify Formula and all the cells above and to the left of the insertion point are empty, using the = (Formula) field causes an error.

## Example

This example creates a table with three rows and three columns at the beginning of the active document and then calculates the average of all the numbers in the first column.

``````Set MyRange = ActiveDocument.Range(0, 0)
Set myTable = ActiveDocument.Tables.Add(MyRange, 3, 3)
With myTable
.Cell(1, 1).Range.InsertAfter "100"
.Cell(2, 1).Range.InsertAfter "50"
.Cell(3, 1).Select
End With
Selection.InsertFormula Formula:="=Average(Above)"
``````

The example inserts a formula field that is subtracted from a value represented by the bookmark named "GrossSales." The result is formatted with a dollar sign.

``````Selection.Collapse Direction:=wdCollapseStart
Selection.InsertFormula Formula:= "=GrossSales-45,000.00", _
NumberFormat:="\$#,##0.00"
``````
