you got me all excited, but unfortunately it gives me an error saying you cannot mix string and numeric data types in arithmetic expressions.
what i've been doing is duplicate special with input graph which duplicates the object with the expression and updates the name. Unfortunately it also duplicates my car position locater which is position constrained to an object of the car which also duplicates.
after i place the object i bake the keys and am able to delete all the extra crap that comes along with duplicate special
it's kind of funny because at first i had the locater constrained to the master null of the car so after duplicated these expressions 20 times i had 20 versions of this fairly high poly car all in the same spot and i had NO idea why the computer bogged down so much.
... le sigh...
if anyone knows the answer still, would be much appreciated
