Hi
I'm fairly new to this but grateful for any help. I need a warning or message box to pop up and stop invalid data being entered. If the user enters a value in a range (C31:U41) that causes a negative value in another range (C45:C55), then this is invalid data and they need to try again with correct data. Hopefully there's a simple answer to this. |

Data / Validation / Custom / Formula : =C45=0 Also see Input msg & Error alert tabs Copy (or drag) C31 down to C41 Regards, Peter T "Cooie" wrote in message ...
