Forums Scripts & Popups isalnum problem

on *:TEXT:!sin*:#: {
if ($2 isalpha) {
/msg $chan Error - 1
}
elseif ($2 isalnum) {
/msg $chan Error - 2
}
else {
/msg $chan $sin($2)
}
}

!sin pie
gives me "Error - 1"

!sin p1e
gives me "Error - 2"

!sin 45
gives me "Error - 2"

$2 is "45" and does not meet the requirments for (letters AND numbers), why does it return true?

I have tried ($2 !isalnum) and it works for "45" but does not catch "p1e"

Use this

if you want just alphabetic use isalpha
if you want just numerics use isnum
isalphanum will look for either alphabetic or numeric, requiring one or the other, not both.

"isalnum" checks for letters AND numbers. As long as there is a letter or a number or BOTH, it would return true.

Yeah, I know...bad phrasing on my part...apologiies to anyone else that got confused.
