Justin: I believe the error returns on this line
mmc.setAttr(setFkMdn+".input1X",jntLength)
Eduardo: if the above is correct, I'll assume that the jntLength variable
is the one getting the list. I tried adding the [0] at the end of it, but
it returns a "TypeError: 'float" object has no attribute '__getitem__'
again, the odd thing is that it works perfectly well when it's the leg
joints that need the stretch FK, but not the arms.
