How do I identify an object that I pass into a function?

In my case I have 6 movieclips and 6 corresponding text fields (all 12 objects are on the main timeline) and the movieclips are named thumb1\_mc, thumb2\_mc, etcetc, and the text fields are named text1, text2, etcetc.

I have a method:

mcl\_mcl.onLoadProgress = function (targetMC, loadedBytes, totalBytes)

in which I need to change the appropriate text file’s text depending on which movieclip is targetMC.

The trouble is I can’t find a way to distinguish which mc it is, so I can’t pick which text file to change.

I tried using properties but that doesnt work because everything about the movieclip gets obliterated the moment I load something into them.
