Hi Wendy, Jen here. To be able to allow folks to select a size, this can be accomplished by creating another ticket for the t-shirt and adding a custom question within the ticket for them to be able to select from a particular size. Or, another way to accomplish this would be to add a custom question to an existing ticket asking the participant to select their size and then adding the t shirt as a deliverable. I am you dedicated account manager, so I will reach out to you personally to discuss this with you and get you set up in a way that works best for. 😊
