Thread: macros programming

I would check to see that the condition is met BEFORE writing the userform values to the worksheet and prompt the operator if the sum of values exceeds the limit.

Here is the basic approach, code assigned to the command button:

 Option Explicit

Private Sub CommandButton1_Click()

    Dim n1 As Long, n2 As Long
    
    n1 = Me.TextBox1.Value
    n2 = Me.TextBox2.Value
    
    With Me
        If n1 + n2 > Sheet1.Range("A1").Value Then
            MsgBox "exceeds needs"
        End If
    End With

End Sub
