Responsive Design - Time not working when converted to a mogrt for Premier Pro

Having reread this article have I think I have miss understood the purpose of this feature within PP?

It makes the file extendable but if my outro happens at 7secs it won't then move to 20secs, if I stretch it out it will stay at the 7secs. Compared to if I didnt have protected regions you wouldnt be able to extend the file without manipulating the intro /outro animations.

But what I am looking to do is have it so the mogrt file can be extended or shorterned and the outro moves with it. i.e.if the outro happens at 7secs and I need it to happen at 20secs I could extend the mogrt file and the outro moves to 20secs.

Is there a way I can do this using a different method? No animation is happening between the intro and outro.

I am trying to hand these files over to other team members (who have little/no experience of AE) to make it easy and flexible for them to use these assets in PP.

there are two expressions used for the drop down menu control

if (thisComp.layer("BG Control").effect("Dropdown Menu Control")("Menu")==1) {
100
} else {
0
}

if (thisComp.layer("BG Control").effect("Dropdown Menu Control")("Menu")==2) {
100
} else {
0
}

Thnak you for responding. Didn't realise about the 3 protected regions, I saw a tutorial that used it. I took them all off and reapplied with just two (intro and outro) and it is still not working.

Any other suggestions?
