Excel VB user form issue when passing values to sub

Im stuck on trying to get two values (a string, and a checkbox) from an Excel user form to another Sub. Receiving 'Object Required' on the User Form code. I have researched and tried different methods to no avail. My codes are below:

User Form:

Public Sub UserForm_Initialize()
    EditForm.Show
    Dim MgrNotes As String
    Dim Deactivate As Boolean
    MgrNotes = tbMgrNotes.Value
    Deactivate = cbDeactivate.Value
End Sub
Public Sub btnSave_Click()
Call OnSave(MgrNotes, Deactivate)
End Sub

General Module:

Sub OnSave(MgrNotes, Deactivate)

Dim cnn As New ADODB.Connection
Dim iRowNo As Integer
Dim StockUnit As String
     
With Sheets("Sheet1")
    cnn.Open "my connection string"
        
    'Read Stock Unit # From Selected Row and Run UPDATE Queries
    iRowNo = ActiveCell.Row
    StockUnit = .Cells(iRowNo, 1)
    cnn.Execute ("UPDATE Table SET fMgrNotes = '" & MgrNotes & "' WHERE (StockUnit = '" & StockUnit & "') UPDATE Table SET ActiveFlag = 0 WHERE " & Deactivate & " = TRUE AND (StockUnit = '" & StockUnit & "')")
    
    'Close All and Cleanup
    cnn.Close
    Set cnn = Nothing
    Set iRow = Nothing
             
    End With
End Sub

The Call statement line is where the error occurs.

Thanks in advance.
