Hi Fettertiger

I'm sorry for all that
The sheet is protected to unable other cells to be selected... I just forgot to tell you the password, which is "pass".
The complicated part is there because, as you can imagine, I'm not an expert on VBA so I just place there what seams to make sense... sometimes wrong, I believe

This is working perfectly! Thank you so much!
I just added a "Sheet1.Protect" to you code, changed the buttons names and compiled all the copy macros.

Reference Guide.xlsm

Can I just ask one more thing?
When I click a radio button the text is copied and I can paste it anywhere except another excel file. Somehow the clipboard is "cleaned".
Is there something (wrong) in my modules that is causing this?

Once again, thanks a lot!
