I’m not getting this. I want to pass a single item (number) from a source to a destination window. On the button I’m using to open the target (the event handler) I click the Pass Parameters box and enter a property (label text) on the source window. I can’t seem to figure out the ‘Parameter Name’ value. I assume that’s the property on the destination window but every combination I’ve tried causes an error. How do I accomplish this?
