[Zope] problem with REQUEST.set

[wombat_harness@hotmail.com]

hey everyone,

i am having BIG problems using REQUEST.set within Zope. I am trying to
dynamically build a URL to redirect the browser to using the following
code:

<!--#call "REQUEST.set('jumpToBase', '../foodirectory/index.html?member
Num=' + userID)"-->
<!--#call "RESPONSE.redirect('jumpToBase')"-->

but this is throwing back an error on the REQUEST.set part, the error
looks as follows:

Object: REQUEST.set('jumpToBase', '../foodirectory/index.html?memberNum
=' + userDetails))
File <string>, line 0, in ?
TypeError: (see above)

The userDetails variable is a INT value pulled from a database and i
cannot understand why it is falling over on this!!

Does anyone have any thoughts?

Cheers,

Wom..
