Using Access VBA code to copy between unbound- and bound fields

I have 2 fields in an MS Access form "BTKForm" sending and picking up data form a bank terminal.
Code is executed by clicking a Button on the form.

Field 1, "IssuerID", is an Unbound field picking up a code from the bank terminal. It's numbers between 0 and 100, representing the Card provider.

Field 2 - "IsID", is a value field linked to a table.

I want to take care of (save) (copy) "IssuerID" in to "IsID".

I have been struggling with the problem for a long time.
Nobody have so far been able to help me.
Please, can somebody help? :banghead:

Code is:

Code:

 Public Sub TransferAmount_Click()
Set BAX = CreateObject("BankAxeptSrv.BankAxeptAutomation")
If BAX.Connected And BAX.LicenseVerified And Not BAX.BankMode Then
Dim amnt As Long
Dim cashb As Long
amnt = Round(Amount.Value * 100)
cashb = Round(Cashback.Value * 100)
If BAX.TransferAmount(amnt, cashb) Then
While BAX.BankMode
While BAX.GetNoOfDisplayMsgs > 0
DisplayMsgs.SetFocus
DisplayMsgs.AddItem (BAX.GetDisplayMsg)
DoEvents
Wend
DoEvents
Wend
While BAX.GetNoOfPrinterMsgs > 0
PrinterMsgs.SetFocus
PrinterMsgs.AddItem (BAX.GetPrinterMsg)
DoEvents
Wend
If BAX.TransactionOK Then
TransactionStatus.SetFocus
TransactionStatus.AddItem ("OK")
IssuerID.SetFocus
IssuerID.AddItem (Str(BAX.GetIssuerID)) ' Getting IssuerID from bank terminal.
Dim lPauseTime As Long
Dim lStart As Long
lPauseTime = 3 'Seconds
lStart = Timer
Do While Timer < lStart + lPauseTime
DoEvents
Loop
Me.IsID = Me.IssuerID
DoCmd.RunMacro "Auto A kort" 'Closes the Form and printing a Check.
Else
TransactionStatus.SetFocus
TransactionStatus.AddItem ("AVVIST")
IssuerID.SetFocus
IssuerID.AddItem ("99")
DoCmd.RunMacro "Avvist 2.BTKForm" 'what is done if tranaction is dismissed.
End If
End If
End If
End Sub
