Run macro when 2 cells are equal

[R.Thynes]

Mr. Excel,

I am using MS Excel 97 as a data acquisition program. A serial device is sending data to a specific cell (4,6) via DDE. The numeric value of this incoming data varies between 0 and 360.

I want to execute a macro when the incoming data (the data in 4,6) becomes equal to a preset constant that I have placed in another cell (4,8).

This may be a simple task, but I have not found a working example from the FAQ lists yet.


Cordially,

Russell Thynes

Put the following code in the module for your worksheet that contains the cells in question:

Private Sub Worksheet_Change(ByVal Target As Range)
Set Target = Cells(4, 6)
If Target = Cells(4, 8) Then MsgBox "Cells are equal"
End Sub

Replace the Msgbox function with the Call function and your macro.
