Using jquery to auto select a radio button doesn’t trigger Conditional Fields

Im wondering if somebody can help here. Im using a script to detect the referring page which auto selects a radio button (one of four) based on their referring page.

Basically if they come from a page about House Removals and click on a link to GET A QUOTE, I’m wanting the quotation form to auto select the house removal option (rather than say Piano Removal or Single Item move).

The script is working and it does select the right Radio button based on the referrer, but Conditional Fields doesn’t seem to notice the auto selected option and therefore doesn’t load the correct conditional form fields.

So I guess I’m asking, can I call the conditional fields script or process, using jquery or similar to make it react to the selected radio button. My guess is that conditional fields is just listening for a mouse click or a touch event before it reacts.

Thank you.
