insufficient parameters would indicate one side of your IF statement is missing (or null). You might want to verify that everything in the IF evaluates to something. If you use $nick, make sure $nick has a value (echo -a Nick: $nick right above the IF line). If you have something else, include that in the echo. Test what you have in both sides of the IF statement. Both sides meaning- if (side 1 == side 2) {}

Beyond that, I'd suggest posting the entire event you're using and any associated aliases so someone can check it for errors.
