Liner Slipping from Coping

[nutmegax]

Thanks for all your help but I am still not sure what to do. I have an inground vinyl liner pool and the coping looks like half of a white metal pipe that is laid vertical from the cement deck down the side of the pool (like 2 inches). The liner goes up the wall and the top of the liner has an inch or so liner trim that tucks into a very small gap between the top of the liner (pool wall) and the coping. I don't see a track just a gap a little bigger than a butter knife that the liner is tucked into. It looks like it just needs to be pushed back up into that gap but I don't know how to do it and keep it there.

Thanks again,

Mary

I believe that gap is the part where the liner goes. Can you take and post a picture? I will take a shot of mine and post it later today. I just wrestled the liner into that butter knife width space - it took a little wrangling, but it got in there.
