error 2465 cannot find field forms

[Guest]

I have created code in VBA that gets tha value from a field on the current
form called prijs. blAlles is a boolean that is set earlier in the code.
The system stops because the value from prijs cannot be found.
I tried prijs and prijs.value

if prijs or blAlles then
...
end if

now on 2 PC's this works, only 1 PC gives error 2465.
I tried to repair and reinstall access, also installed service packs 2 and 3.
All without succes.

What could be wrong?
