If A1 in Sheet1 corresponds to Sheet A1 in Sheet2, and you want the

Sheet3. Now move your mouse to the lower right hand corner of A1. The
cursor shape will change. Click, hold and drag down to row 100, and release.
If your formula is in B1, because you have say descriptions in A, which
correspond to the descriptions in the other 2 sheets, then merely double
click in the lower rightn hand corner of B1, and it will copy the formula
down to B100

That did it, Kassie.

Thanks!
