Peter,

As a matter of fact, the procedure : Private Sub ButtonGroup_Click()
is located in a class and I am calling it
from the very same userform ...
and in one instance, it has to call itself i.e. a CommandButton Click
will trigger automatically the next
CommandButton Click ...
Should I use your recommendation :
sProc = "CommandButton" & i & "_Click"
CallByName Me, sProc, VbMethod

Thanks again for your precious help
Cheers
Carim
