Why do you want to store the strings level1, level2, level1000,.. ?
I would only store the number with a global number variable 'current_level' or perhaps I don't understand the question..
What also should work is - if you have "levelnames" - is storing at the beginning all names in a global 1d-Array eg:
myLevelNames_Array= ['The first one','Second','Final Stage']
and load the right value on start of each layout to the current Layout:
LevelLabel- set Text -> myLevelNames_Array.At(current_level-1)
