[chimera-dev] declaring an integer to be used for the model and select command

Hello there! I am trying to write a python script for chimera to rotate one molecule then translate another molecule to the right. I can get the code to work when I say use select 0 and model 1. But I want to define functions Rotate and Translate and be able to parse an integer value for the model numbers: Example def Rotate (0) where 0 would be the value of a variable called model inetger then later the function would have the code runCommand("move x -1 model #modelinteger") but when I try to compile chimera says model integer is not defined. I define it outside the function as modelinteger=0 but still the same error message shows. Basically how do I get chimera to understand that my variable modelinteger is indeed an integer?
