I have a userform whose image is attached below.

What i need is when i press the submit button, it should promptv if there is any textbox left empty in the userform.

Here is my code:

Private Sub CommandButton1_Click()

Dim intTextBox As Integer
For intTextBox = 1 To 2

If Controls("TextBox" & intTextBox) = "" Then
MsgBox ("TextBox" & intTextBox & "blank. Please enter relevant data!")
Exit For
End If
Next intTextBox

End Sub

I am getting error at If Controls("TextBox" & intTextBox) = "" Then as could not find the specified object.

Kindly review and advise.

In order to find which TextBox is left empty, you need to loop through all Controls in your user_Form. Then, for each Control you need to check if it's type TextBox >> if it is, then check if it's empty.

Code

Option Explicit

Private Sub CommandButton1_Click()

Dim ctrl As Control

' loop through all controls in User_Form
For Each ctrl In Me.Controls
    ' check if "TextBox"
    If TypeName(ctrl) = "TextBox" Then

        ' if current TextBox is empty
        If ctrl.Text = "" Then
            MsgBox ctrl.Name & "blank. Please enter relevant data!"
            Exit For
        End If

    End If

    ' check if "ComboBox"
    If TypeName(ctrl) = "ComboBox" Then

        ' if current ComboBox is empty
        If ctrl.Value = "" Then
            MsgBox ctrl.Name & "blank. Please enter relevant data!"
            Exit For
        End If

    End If
Next ctrl

End Sub
