How to install Swisscom spline

A home owner from New Jersey says:
I purchased flat spline, fiberglass screen,and tool from Swisscom, in order to rescreen my forever door. I am uncertain, as to what side to put against the screen. I have reviewed both videos, the close up video tells you to slide it under the lip of the frame, but not which way to put down.

Thanks for your patience during this busy season. I recommend that you review the close up video we have for the 55-109. It shows to install the lip into the inside lip in the screen frame. These Forever door screen repairs do take a little getting use to, trust me, but there isn't really a trick to it. It just takes a steady hand and a lot of patience.
