Hi Carl,
Thanking you in heaps for this. Awesome to see a staff badge on your icon as well. Congrats for this. And for this explanation as well. Clearly demonstrates the love and respect that Greensock absolutely deserves with this forum. I realised when I posted that the time over your way was 7.45am, it was already late afternoon and had spent most of the morning trying to snip away at the addLabel issue!
Anyway, I stuck in the function to update the text on the scrubbers drag function so that it fired the onStart method when the user lets go. It's pretty crude compared to your super in depth explanation! I hadn't looked into or read anything about the callBack method. This is fantastic stuff!!
If I'm reading this right, I can essentially insert/append a function into my timeline? Niiiiiice. I see some used for this already in my flash adventures!
Thanks again Carl, outstanding work yet again. From over in the English Isles, I tip my hat to you sir!
