remove spaces from string

[Thunderstone]

I'm using the MetaSearch script with Webinator, and I want to remove the beginning and trailing spaces, if any, from the query string. I've tried numerous different attempts at doing this, using REX, SANDR, and SPLIT, but none have been successful. Any ideas out there?

Thanks.

Try
<$s=">>= +" " +>>=">
<$r="" "">
<sandr $s $r $q><$q=$ret>
