Globals don't work? Or are they just per layout then? hmm
What about creating a new event sheet with variables that'll store the info you're trying to pass and including that sheet in both layouts' events. Then just update in one layout and read the info in the other. I'm pretty sure there's a better way... not even sure if that would work but logically... it should Might be a pain if you have craploads of variables you need passing from one to the other..
That could work quite well i reckon.
Global variables are useful but what if i want to share more than just a few variables, would be easier to share an event sheet, didn't think of that
