just found mickericksons solution, as below if it helps. Can anyone help me change it so it does not affect existing sheets, only new ones on opening, or is there another solution?
If this routine in put in the ThisWorkbook code module, every time a sheet in the workbook is activated, the formula in Master sheet, cell G6 will be put in G6 of the newly activated sheet.
The name "Master" and "G6" should be modified to fit your particular situation.
Instalation instructions:
Open the VBEditor, View the ProjectExplorer, open the Microsoft Excel Objects folder, double click the ThisWorkbook icon, copy/paste the code into the window which will appear. Close the window, Exit the VBEditor and return to Excel.__________________
