Conditional for what error (STANDARD_ERROR template)

[Dr.CustUmz]

Inside the STANDARD_ERROR template the no permission error has its own condition, yet every other error is simply defined by $errormessage

does anyone know any of the conditional for the other error pages?

This is the no permission one:

<if condition="$show['permission_error']">

(not authorized)

I need:
- Invalid Forum
- Sorry not accepting post
- And any other error messages

So that I am able to differentiate between them within the STANDARD_ERROR template.

Things I have tried:

<if condition="$show['badlocation']">
badlocation
</if>
<if condition="$errormessage = $vbphrase[invalidid]">
invalidid
</if>
