Progressive String Dilemma

[DisneyBoy]

What I need to do is have the player of the game click on a
text file and have it carry over to another frame. No problem there, all I have to do is use a global string. But what I need to do is this, if the there is no text files in the second frame, I need to change string #1, if string #1 is filled it needs change string #2, if both string #1, and #2 are filled, then use string #3, etc etc. How is this done.

You can use fastloops and the ability to get Global Values/Strings by index rather than name.
