Problem with Ghost modding? (Arithmetic Operation)

[tazzyopz]

So I've found a few addresses in Call of duty ghost. And I have modded them perfectly fine with Cheat engine. But when trying to write it in VB I get an "Arithmetic Operation resulted in an overflow." Can anyone help with this?

here is picture:

Share the "WriteInteger" function's source code perhaps?

I did a bit of research and it seems that the code only works on 32Bits process.
