Allowing Multiple Form Views

I have four main forms in my program. The first is a sign in screen, the second(screen selection screen) form allows user to select between the other two forms(Select Screen and Verify Screen) or exit. Users can select in the select screen they then return to the Screen selection screen. However, if the user has selected some items the vierification screen does not show them. Also once the user has already been to the selection screen, when they select the Selection Screen again on the Screen Selection Screen no information is loaded. Can anyone help me with this? I know this could be confusing I'll be happy to clarify if needed.

If you post the project, it will easier for us to understand your problem.

Anyway, by what I've understand,

If you unload any of the last 2 forms, all changed data in them will be lost.

You can,
1.) save those temporary data in a global-variable/temporary-file and load them everytime those forms gets loaded.
or,
2.) You can Hide/Unhide the forms instead of unloading. (needs more memory)

I would guess that you are unloading the forms someplace and when you call them again they are reinitializing.
