Man, no offense, but this is the most terrible project I've ever seen. It's a total mess..
It's absolutely impossible to figure out what's going on and how is it supposed to work.
You have 20 sprites and all of them are called "SpriteXX"?
Layout has 11 layers, most of which consist of just 1 object?
Variables called "obj" and "src"?
And your project size is 40Mb?
I'll try to guess what your problem is.
You want your animation to stop on frame 16. After that user should click red button and the animation will continue. Is this right?
Your mistake is that even when you restart animation, it gets stopped again on frame 16.
Here is one of the ways to fix it:
The proper way to do it would be splitting your animation in two. After one animation is finished, wait for user to click the button, then start the second animation.
