Maybe it's nonsense - but i often run in the issue that variable (thumbs for example) are prefilled with a previous vie in a scin and the variable stays filled until there is a new value. Special when it comes to conditions it gets trocky to work around this. Actuall example in my fullscreenvideo - If I get a ClearArt from a previous series and switch to one without any clearart it still is going to display the old one. So I thought - why not having a function to call at the start of the xml clearing all or specific values?
