Ordinal position changes every iteration

Hello All, 

I am working on a script where the ordinal of one of the correlated values changes every iteration. One iteration the necessary value may be ordinal=27...next iteration the ordinal=11...next iteration oridinal=13. Is there a way to capture the exact value needed? It is a very "weird' application because the left/right boundaries change as well so I cannot extend the left/right boundaries to be captured. I am using loadrunner 12.53 with Windows 7. Thanks to anyone in advance for their help.
