code:
"C" & selector.backcolor = me.backcolor
If selector =< 4 then
selector = selector + 1
end if
I really can't see how that's meant to work. It's not logical, and it obviously doesn't work as mwe has said three times it highlights it in red.
What is ""C" & selector.backcolor "? You can't dynamically concatenate a backcolor onto the end of a string and set it to something. You make no sense.
