I have a code that is suppose to do the following:
You type a single number into the input box then you hit the plus key. This will make that number be added to what ever is in the display box. Then you type a new number into the input box and hit the plus key again and now this new number will be added to what is in the display box and the sum will again be put in the display box. You must use the if statement and the plus key does not show up on the form.

Private Sub txtInputBox_KeyPress(KeyAscii As Integer)
IfChr(KeyAscii)= "+" Then
KeyAscii=0
txtDisplayBox.Text = Val(txtDisplayBox.Text) + Val (txtinputbox.Text
txtinputbox.Text = ""
End If
End Sub

Now the code works!! but there is not way of telling the user to enter any numbers or no way of telling the user to press the plus key, and I'm not sure how to create the forms. Please help
