Forums Scripts & Popups If/Then question

So I'm having an issue with a script snip.
This line

if ($2 = null) {$2 = 6}

I'm using a wrong variable. The idea is if no other number is set for $2 I want $2 to equal 6. Otherwise, it's the number set in the script command.

Use this:

if ($2 == $null) { var %2 = 6 }

$iif($2,$2,6)

And you get 6 when $2 is 0

Never use $iif unless speed execution doesn't matter and it really avoids repetition

I like Sakana's idea

Ok,

Yeah but you are still using $iif, the suggestion was to never suggest to someone to use $iif unless speed execution doesn't matter AND it makes the code clearer/avoids repetition, because $iif is much much slower than /if

On the same lines as this, if I want a different variable set if letters and not numbers are used, how would I do that?

I'm looking for the variable segment that states that, but I cannot find it.

As in..

if $2 is a word or series of words and not a number then.. the script does another thing...

Looking for the variable that means "no numbers included, only the alphabet"

You need a regular expression. This one does what you want (only triggers if all characters in $2- are either letters or spaces)
