>Never thought of that, I'll give a looks, Thanks. With what you've given me how do I indicate what column?

Again, try it with a macro.
Normally you would first select a cell or a range, then apply the format. Doing the macro and reading the code is very instructive.

Depending on your code, you could use xlApp.ActiveCell or define a range:

loRange=xlApp.Range("A1").Select

then apply the format to the selection.
