[pmwiki-users] conditional markup "empty variables" or length=0

Good morning!

I tried to avoid a problematic link in a pagelist template via:

==>|| (:if2  equal "{*$Trail}) "  "  
":)[[{>$FullName}?Trail={*$Trail}|$[next]]][[{>$FullName}?Trail={*$Trail}|>]](:if2end:)Trail=-{*$Trail}  
-||

(whole pagelisttemplate at bottom of post)

The results are the same:
http://orientalcarpetstudio.com.jovinus-meta.net/Carpet/10005?Trail=Category.Gross
http://orientalcarpetstudio.com.jovinus-meta.net/Carpet/10005?Trail=

the variable seems to be as expected (right on the line with next and Prev).
I tried several ways to compare, until now something seems to be not correct.

Can anybody help me to correct the condition above?

thanks in advance
regards
