[RESOLVED] [vBA][Access][Urgent :)] Login Code within frmLogon not working in subform

[emdiesse]

I have a form called frmIndex with a subform called IndexFrame. IndexFrames Source Object is frmLogon. The logon form contains the code below.

When the database is opened frmIndex will show and the user wishing to logon will have to enter his username and password in the textboxes provided
(txtUsername and txtPassword) Then click cmdLogon. This will run the logon code.

If the username and password are correct the subforms Source Object will change to frmMenu thus displaying the menu form within the subform. To do that
this bit of code was used.

Forms("frmIndex").IndexFrame.SourceObject = "frmMenu"

The bit I need to change is highlighted in red (I believe this is all).
When I use a correct username and password and click logon to run the logon procedure (below) I recieve this error:

Run-time error '2465'
Microsoft Access cannot find the field 'frmLogon' referred to in your expression

Please help me change the bits in red so it works. Thanks


This is the code I used:

[Option Compare Database
 
Private Sub cmdLogon_Click()
    ' Set up variables
    Dim dbs As Database
    Dim userstable As DAO.Recordset
    Dim usersRank As DAO.Recordset
    Dim logonusername
    Dim logonpassword
 
    'get data from the logon form
[COLOR="Red"]    logonusername = Trim(Forms!frmIndex!frmLogon.Form!txtusername)          'Refers to txtusername.text within frmLogon within subform/subreport control (name: IndexFrame) within frmIndex
    logonpassword = Trim(Forms!frmIndex!frmLogon.Form!txtpassword)          'Refers to txtpassword.text within frmLogon within subform/subreport control (name: IndexFrame) within frmIndex[/COLOR]
 
    ' open database
    Set db = CurrentDb()
 
    'open the table
    Set userstable = db.OpenRecordset("tblUsers", dbOpenDynaset)
 
    'find the users name
    userstable.FindFirst "username = '" & logonusername & "'"
    If userstable.Fields("username") = logonusername Then
        If userstable.Fields("password") = logonpassword Then
            Forms("frmIndex").IndexFrame.SourceObject = "frmMenu"
        Else
            MsgBox "Incorrect Password"
        End If
    Else
        MsgBox "Incorrect Username"
    End If
End Sub
Private Sub Command11_Click()
    Forms("frmIndex").IndexFrame.SourceObject = "frmMenu"
End Sub
