How are you passing the value in the request.vars?
I'm going to guess that on your AJAX call in the _onChange handler,
you want to specify the parameters. You can do something like:
- ajax( '{{=URL(c='controllerName',f='test_chg',
args=request.args(0))}}', ['firmdrop'],'target' )
You can pass whatever you want in args. If you have values in
request.vars, you should be able to access then like:
- request.vars.variableName
