How can you expect users to know the form names? Don't think I'd do it, but:

DoCmd.OpenForm Me.TextboxName

Or explore http://access.mvps.org/access/queries/qry0002.htm to give you a list of all the Forms in your database... use at peril if you're trying to lock down some forms/only open some after others are up!

If the list isn't too long and not expected to change often, you can just hand-code a combobox to do the same thing with only the forms you want them to open directly.
