Sorry for the delay getting back to you..
Yes!! This is exactly on the right track. Thank you.
Next thing to do it get the Concept Icon to appear first with the panel, and hold the icons with clicks also... I see you're using 'Panel' to control them - what's the equivalent for the icons?
Ok, i will look at mouse events.
Code to display default panel and icon requires a new line.
// Default Panel: first panel
sym.getSymbol("Concept").play('Over'); // <== new line
Wow I think that's done it! Thank you so much!!
There's a tiny glitch on the arrows and text for Motion.. I've tried to fix it but I can't seem to see anything wrong or different in the coding :-/ Can you see it too or is it just my end?
Really appreciate all your help on this!! Do you work for Adobe?
1) I looked at the "Motion" button.
Well, i assumed buttons were identical and copied and pasted code.
But it was a false assumption. "Motion" timeline is special.
Symbol: "Motion_1", trigger @125 ms: sym.getComposition().getStage().getSymbol(nextPanel.replace("_1","")).stop(1000);
I replaced 875 ms by one second.
Ah ha! My bad, I didn't realise they weren't all the same length - that was a trickier animation to do. Fixed it.
Oh, well I really can't thank you enough for all your help! Very generous
