how i send to a globel model a string and how i get it back in access 2010

Technically you don't "Get" or "Send" values to/from a Module.

You typically can retrieve a Public Variable using a Public Function.
...And store values in public variables.

Something like this in a Public Module:

Public lngpubCustomerID as long

Public Function GetCustomerID () as long
    GetCustomerID =lngpubCustomerID
End function

Now you can set the public variable from anywhere in your project, something like this:
lngpubCustomerID =me.cboCustomerID
...Then retrieve it with this:

SomeThing=GetCustomerID()


Note that you may also have to implement a system to "reset" the variable.

The danger here is that you must tightly control where, when and how you set the Variable, or things could get confusing.

Thanks for Your Answer sorry for the delay i was outside the town...


iry the code that you give but its not working

this is my code in the form that i store the variable
Public Sub Command21_Click()
Dim strFormName As String
strFormName = Me.Name
GetFormNameSt = strFormName
End Sub

and this is my public module
Option Compare Database
Public GetFormNameSt As String
Public Function GetFormName() As String

GetFormName = GetFormNameSt


End Function

and in the other form where i want to retrive the variable i wrote this code in a command buttan
Private Sub Command0_Click()
Dim b
b = GetFormNameSt
MsgBox b
End Sub

but the problem that i get a blank msgbox without the form name
