This is how to use the Field Calculator...
Open the feature class "table" while in ArcMap
Right click "acres" field select calculate values
In the field calculator dialog box check the advanced tab
Insert the following code in the Pre-Logic VBA Script Code box
Dim dblArea as double
Dim pArea as IArea
Set pArea = [shape]
dblArea = pArea.area/43560
Insert the following line in the "FIELD" box
dblArea
Hope this helps....
