Hey, nice work with what your trying to achieve even though it may seem simple (Looks wise) but it really isn't. And to answer your question it won't be easily practicable to achieve, probably unless you are great at math.
Right thanks, but this just spawns the GUI then scrolls it up.. I want it to spawn scroll down, stay for like 20 Seconds, then scroll back up then delete. (Destroy Element)
Right, I used the example from the wiki just for testing purposes, but what I am attempting to achieve is to, do this.
The gui will come up, showing only the title bar.
Then ease down unrolling showing the whole window.
This is how it should look afterwards, then when closing it would just scroll back up.
