u are just wrong..
Quote:

.timerclrclst -o 0 300 if ($!ibl(#channel,0) >= $calc($maxbans - 5)) clearlist #channel

will first evaluate it, and make it like this:
"if ($!ibl(#channel,0) >= 95 clearlist #channel"
which is wrong syntax for if and will give u an error "if invalid format" when it's triggered.
