i'm trying to set it so depending on with radio box the user picks depends on what the variable is set at. I'm new at this, got the dcl working great, but the lsp is still a problem. The code so far is (get_tile "side" "1" "(setq blockname "c:\side.dwg")") (get_tile "end" "1" "(setq blockname "c:\end.dwg")") Any pointers would be great
