Before posting code that does not work, it is a good idea to reduce to 
to some minimum needed to exhibit the problem. If you had done that, you 
may well have found the answer.

In this specific case, you should have searched for all lines making 
assignments to the names causing a problem. This is easier to do by eye 
with a minimal example. Or, use a search function for 'T0 =' (or 'T0=' 
if needed, but it is not) with Find Next and the second hit is the 
offending line ("T0 = initCost*0,1").
