So close! Please help!
I created a new page for managing product options. The ProductID and OptionGroupID are passed as URL variables.
When a user selects an OptionGroup, the options appear with checkboxes. I used the "manage relational table" behavior to store the information. I was careful with the wizard following the instructions.
I'm not sure how to make the checkboxes work with the relational table. If you are able, please review the attached file. Any assistance is always greatly appreciated.
