[xquery-talk] Problem with "let" statements in an xquery function

I'm puzzled about this function I'm working on:

declare updating function
       $a as element(),
       $b as xs:string
       let $c := $a//some_element[.=$b]/..[another_elem='foo']
       let $d := $a//anoher/element

       if( exists($c) )
               replace value of node $c/xxx with $d

The problem is, those "let" statements aren't working... if I check the
value of $c or $d they're null. And the xpath expression I'm using is valid.
Based on the W3 specs I understand those "let" declarations are valid:


What am I missing? Should I assign those variables in some other way? I
tried using "declare variable" instead but that didn't work either.
Thanks for any comments, I think I could use an extra pair of eyes. :-)
