Hi Steve You just have to use the SelectionInfo function in MapBasic.
If SelectionInfo(SEL_INFO_NROWS) returns zero then nothing is selected. Remember to include "MapBasic.def" into your .mb file to get the "SEL_INFO_NROWS" to work or else use SelectionInfo(3) instead.

I want to run a quick routine which works fine but if I don't have anything selected and I hit the button to run the routine/MBX the whole thing craps out. Do I need a check or just an OnError command? I was thinking something like; If Selection = true then Run MBX Else Note "Nothing Selected" I am just having trouble coming up with the correct syntax.
