Hi Zachary,
The list of all the available Variant control labels can be found by selecting the desired Variant subsytem and then executing the command:
out = get_param(gcb,'Variants');
"Variants" is a hidden parameter and is not listed when we search using "ObjectParameters" or "DialogParameters" as arguments. This issue has been forwarded to our developers and it might be resolved (i.e. "Variants" made visible) in a future release. Coming back to your question, you will see that "out" is a struct with fields "Name" and "BlockName". The list of your labels will be stored in the "Name" field. Hope this helps.
