Hi,

this must be a frequent question but I couldn't find an answer to it on the website.

I've got following velocity template:

#set ($tempLink = "http://${subdomain}.tradedoubler.com/tr?a=${aId}&c=${cId}")
#if ($pId)
  #set ($tempLink = $tempLink + "&p=${pId}")
#end
#if ($preurl)
  #set ($tempLink = $preurl + $tempLink)
#end
$!{tempLink}


The fact of the matter is: Even though neither $pId or $preurl is null (I verified this and
yes, it does enter the #if-blocks) the resulting tempLink is always

http://se.tradedoubler.com/tr?a=239&c=39433

The question is: Why don't the subsequent #set-directives change the value of $tempLink?

Thanks in advance,
Daniel Pfeifer
