You cannot change a worksheet from within a function. A function can only
return a value which replaces its call.
You may try a Sub, but you'll have to figure out which event(s) should
trigger it.
Also, you'll have to pass a range as one argument or use a different
construct. But Range("x:y") will not work.

Maybe you can post what you're trying to achieve.

i am trying to create a function that will change the calculation of each
cell in a range. i want to be able to call this function using different
ranges at different times.

Public Function DivideRange(TheRange As Range, c As Range)

Set TheRange = Range("x:y")
For Each c In TheRange
c.Value = c / 1000
Next c

End Function

I am not sure how to get this to work. I have posted what I have created
thus far. Any suggestions would be helpful.

Thanks
