thadacto,
I thought I had a solution, but then realized I don't understand the problem. Are you wanting to:
1) Activate the sheet (coming from another sheet)
2) See what cell has been activated (not what cell you activate, but the last cell clicked on that sheet before you reactivated it)
3) Depending on that, change the values in P50?
Or, are you wanting to:
1) Activate (select) a cell on the active sheet
2) Depending on that selection, change the values in P50?
If the second one is right, I think you;d need to use a Worksheet change event:
