 * Hey Guys,
 * first: s2member is great – i love it!
 * currently i would like to implement the tracking code (via Integrate Modification
   Tracking Codes field in backend) for account modifications. i want to test whether
   a replacement code is empty or not. if the replacement code (%%tid%%) is empty,
   i have to load a different tracking code.
 * if(%%tid%% == “”) {
    <img src=”[http://tracking-url.com/code.cgi?pp=123455&tid=%%tid%%&cashflow=%%regular%%&tax=1.19&goods=%%subscr_id%%&#8221](http://tracking-url.com/code.cgi?pp=123455&tid=%%tid%%&cashflow=%%regular%%&tax=1.19&goods=%%subscr_id%%&#8221);
   width=”1″ height=”1″ /> } else { <img src=”[http://another-tracking-url.com/code.cgi?pp=123455&tid=%%tid%%&cashflow=%%regular%%&tax=1.19&goods=%%subscr_id%%&#8221](http://another-tracking-url.com/code.cgi?pp=123455&tid=%%tid%%&cashflow=%%regular%%&tax=1.19&goods=%%subscr_id%%&#8221);
   width=”1″ height=”1″ /> }
 * how can i do this?
 * greetings
