What is 'var'? I don't see anything by that name in your program, so I guess that you mean "some variable". It would help if you said which variable was changing unexpectedly. Also, you say the problem disappears if you "move the data close to the effected Var". What "data" are you talking about moving?

It would help if you explained the problem a little more completely.

It would also help if you posted all of your program instead of just part of it.

It would help even more if you posted two copies of your program, one where you have the problem, and another after you have made the problem go away by "moving the data close to the effected Var".

When you post your programs, be sure to cut and paste them from your original source so that you don't accidentally make a typo when typing them into the forum.

Finally, this guide will tell you how to post your code so that the formatting doesn't get messed up.

By the way, it is really good (!) that you want to find the root cause of the problem, rather than just ignoring it becuase you found a crazy way to make it disappear.
