Create Unique ID in ARCPAD Form Code Issue

I'm trying to create a Unique ID that pops up on a custom form I'm making in ArcPAD. This is needed so field workers can include this number on some supplemental paper tables that they carry around.

I've pasted together the following code which mostly works; however, if someone uses the repeat attributes toggle then the "unique" ID is also repeated.

Is there any way to test to see if the repeat attributes toggle is on or off?

I can't find it anywhere in the Object Model.

Here's my code. This runs on the ONLOAD event for the form (sorry for the lack of documentation). This basically just loops through the features and finds the highest number in the ID field and adds 1. If the ID box on the form is already populated this is not executed.

Option Explicit

Dim varUniqueID

Sub UniqueID2
    Dim objRS, HighValue, CurrentValue, objEFPageOneControls, objEditForm 
    Set objRS = Application.map.layers("OFF_ROAD").records
    Set objEditForm = application.map.layers("OFF_ROAD").forms("EDITFORM")
    Set objEFPageOneControls = objEditForm.Pages("Page1").Controls

    If (objEFPageOneControls("IDBOX").Value = "") Then
        If (objRS.RecordCount > 0) Then

            objRS.Movefirst

            HighValue = objRS.Fields("ID").Value
            objRS.MoveNext

            While Not objRS.EOF
                CurrentValue = objRS.Fields("ID").Value

                if HighValue < CurrentValue Then
                    HighValue = CurrentValue

                End If

                objRS.MoveNext
            Wend
            HighValue = HighValue + 1
        End If
        objEFPageOneControls("IDBOX").Value = HighValue     
    End If
End Sub
