Create your control with the image of the arrow [I'm assuming that you don't have a problem creating that - but let us know if you do].
Then in the On Load Event of the Form [Open the 'Property Sheet' and then click outside the actual Form -> you will see that the Selection Typ in your Property Sheet will say 'Form'].
Now - click on the Event Tab, click in the 'On Load' row and click on the [...] to the right.
Choose 'Code Builder' and you should see:
Code:
Private Sub Form_Load()
End Sub
Put something like this between those two lines:
Me.NameofYourArrowControl.Visible = False
When you run the Form - the Arrow will be invisible.
Now, go back to Form Design Mode and in the 'On Change' Event of your 'EndValue' text box put something like this:
Me.NameofYourArrowControl.Visible = False
I hope this helps!
