OK,
I think I understand what you are trying to do (but I may be wrong...)
However, I don't think that you need to make the whole form global, just the individual controls.
Here is a an example of a recent post with an example for accessing the properties of a textbox on a form from a different form. This can be applied to controls, dataset, etc.

Let me know if this doesn't help.
