How to concatenate a variable with a Range

Leith,

Thanks for your response, which made complete sense to me and you understood exactly what I required, however I still get the following error

Run-time eror '1004'
Method 'Range' of object '_Worksheet' failed

I attach the .xlt file and hope you can see what is going wrong. If you cannot, I will be happy without the first 2 letters of Range 'ExIncOp'!

Regards
