hi, I'm having a problem in our case study how will I put all the values inside the message box? Once I click the button, the order must appear on the message box together with the costumer name which is written in a text box. So far this is what I've done. Sorry for the quality. My sister's laptop doesn't have editing software.

You have way to many event handlers...

Did you know you can share handlers?

Example:

Private Sub CheckChanged(sender as object, ByVal e As EventArgs) Handles CheckBox1.CheckChanged,CheckBox2.CheckChanged,CheckBox3.CheckChanged
   If Ctype(sender,CheckBox).Checked Then TextBox.Visible=True Else TextBox.Visiable = FALSE
End Sub

As for the mssg, are you pulling the value from the text box that is visible?

well simple use this.

msgbox(txtbox.text)

and if you have so many txtboxes and want to show the data in masg then you can use this.

msgbox("name:" & txtName.text & vbCrlf & "Age:" & txtAge.text)

hopr this will help you.

Or even

TextBox.Visible = Ctype(sender,CheckBox).Checked
