So, I have been using this topic as a reference point for making an object blink. Because I wanted to cue the blinking based off of a button click, I implemented the Greensock idea. It runs locally, but, when I upload it to our server, it doesn’t work. I get an error “Uncaught Cannot tween a null target.”  I don’t see the shape I am referring to in the directory that needs… however, they have been uploaded to the server. It’s like it doesn’t see any of the Lectora generated objects. Does anyone have any ideas on how to fix this?

I am open to an alternative method to making the object blink…but, can’t use the timer… because, buttons don’t support that action. (So, says the compiler.).

Any help is appreciated.
