Hi, Happy Christmas and Happy New Year.

Lets come to the discussion,
Use Public keyword declare a public variable in a module so that all other modules and forms can access it.

Ex:-

'In a module
   Public sUserName As String

'In a Form (Form1 )
' - Draw a Button (Command Button - cmdSetUser)
' >> Add Form (Form2)
' - Draw a Button (Command Button - cmdShowUser)

'In Form1
Option Explicit

Private Sub cmdSetUser_Click()
   sUserName = "ABCD"
   Form2.Show
End Sub

'In Form2
Option Explicit

Private Sub cmdShowUser_Click()
   MsgBox sUserName
End Sub

But avoid often using global variables.

When u use global variable, u may face some problems .
See this site for detail. It is common for all the languages. So dont use it often.

Dont worry about your project.

Just try out your project, if u have any doubt u post it here.
Definitely not only myself, any one can help you .. but try from your side is very important .. Do well.
