I have the mixingdeck stack and about 6 months or so ago I put a video in it. I’m trying to change that and cannot find where the file name goes.
The instructions say: “To do this, double-click the HTML placeholder in Stacks edit mode (within the MixingDeck stack).”
But all that shows is a rectangle with an X. No placeholder. Don’t remember how I got is in there the first time.
