I need to use radio buttons in a gallery to select a single item. I am wondering if this can work correctly. I have it set up as follows: I have given the items a collection with the respective row item. On the OnSelect of the radio button I set a variable with the selected item. If this variable is filled, the button is enabled for further clicks. Otherwise the button is disabled. The problem now is that although I get the variable filled properly, you can also unselect a checkbox by clicking around and then still click on the button because the variable with the item is logically still filled. I need to somehow check that none of the checkboxes in the gallery are filled and then clear the variable.
