Now, on the overlay form there are two options, to have an open bet against any member or have a bet against a certain member in the forum.
When I click the button I created, I want the open bet field to be hidden/locked and the "certain member" field to be populated with the member that is getting challenged.
Lets say User A is browsing the forum, he comes across user C. Underneath User C 's avatar is a "Challenge Me!" button. When User A clicks the challenge me button, it opens up a form as an overlay. The "Create Open Bet" field I have (on the addon) should be locked or hidden and User C username should be populated in the "Challenge Member"field.
How would I go about doing this
