Re^2: Need help with binding event in Tk

Okay that's where I am a bit confused. I thought since I'd defined my conditional, if it was true, then the show sub would execute, and if not, then the other set of code would execute. Since the colon is there, shouldn't that have seperated the two conditions?

There is no emoticon for what I'm feeling now.

Check perlop. '?:' has higher precedence than '=', so your code is equivalent to: `( ($key eq "year") ? &show($bros->{$data}->[$list]) : $index ) = 0;` [download] And since you didn't want to return any value (not even an lvalue) from the '?:' operator, you would have been better off using a conventional `if (...) {...} else {...}` construct. Using '?:' in a void context can be confusing to a maintenance programmer.	[reply] [d/l] [select]
