[Chameleon] Globals

[Abbott,Arthur]

Ok, I switched over to using a $SESSION variable. Unfortunately I have the same behaviour. When I try to use the value in QueryWidget that was supposed to be set in QueryResults, the value does not change. This is wierd since i know its changing in QueryResult. I echoed the value before and after and the value does change.

  echo $_SESSION['junk'];
  $_SESSION['junk'] = $url;
  echo $_SESSION['junk'];

Using this code, the value of session is changed and i can see the change, yet when im in QueryWidget I dont see the new value.

I wonder, am i trying to use the variable in the wrong place? I am currently trying to use the value inside of the QueryWMouseClick function of QueryWidget. should I be trying to use it someplace else?
