VB script in Excel object in Powerpoint (Urgent)

[epak]

I am really, really sorry, and I know it must be really tedious for you, but could you explain step by step how I would reference, and how I would change the code?

What would a sample address for a cell within an excel table embeded in powerpoint look like? An address that would work in a macro embeded in the powerpoint that can be used by a mouseover or mouseclick action?

I'm very sorry, but it's really urgent..

I don't know if this is right, but under tools/references I checked Microsoft Excel 11 Object Library..

If that is right, now what would I have to do?

Is the address something like..

ActiveWindow.Selection.Workbook(1).Worksheets(1).Range("A1:B5") = "AB"

?
