Hi Raz,
Without screenshots it will be difficult to help you on this point.
You can verrify 3 simple things (that you've probably already checked) :
1/ the variation of the field isn't set on "hidden"
2/ your field isn't in the hidden category
3/ the access isn't set on a too high user group (ex : administrator or super user)
If it didn't solve the problem, don't hesitate to come back with screenshots.
Good continuation,
Ness
