Reference a variable comp name

Hello AE community!

I'm trying to reference to a composition which is duplicated many times.

Let me give you an example:

I have a text layer named "Index" which changes value each time the comp is duplicated

For example, it's value is 1.

a = thisComp.layer("Index").text.sourceText;
x = comp("name 1" & a ).layer("^TV1").sourceRectAtTime(time).height;

I need it to be "name 1 1"

For example, it's value is 2.

a = thisComp.layer("Index").text.sourceText;
x = comp("name 1" & a ).layer("^TV1").sourceRectAtTime(time).height;

I need it to be "name 1 2"

Hope I've made it clear enough what's my problem ☺

Thanks!

Dan the Daysaver, thanks a lot, again!!! :)
