Counting items in a list collector

[kjones2]

I'd Like to create a catalog UI policy that disables catalog variables depending on the number of items in the collector. In my particular example i want to disable a multi line text variable if more than 1 selection is made in the list collector. It seems like it should be a simple thing to do but I'm struggling.

Hope this helps!!!

Great, thanks - that works in a catalog client script with a small modification.

Might not be very efficient way to do but this should work

if(current.variables.groups.toString()=='')

  {

  gs.addInfoMessage('Array Length Is Zero');

  }

  else

  {

  var arrayLength=(current.variables.groups+',').split(',');

  gs.addInfoMessage('Array Length-'+parseInt(arrayLength.length-1));

  }

Note: If needed for client side, just modify accordingly
