I have created a dynamic block (basically a rectangle with wheels in plan view) I have a list of diff sizes to choose from, and a visibility par that either shows the casters on or off not. All of that works great. I am trying to add text that will appear within the block that shows the size of the mobile shelf after I select the one I want from the list I created. So ultimatley the text will change when the block is stretched. Is this possible to do?
