CC Page turn keyframe breaks expression

Hi guys, first post. I have the fold direction of cc Page turn linked to a point control in a external comp (so i can easily control it outside the comp). The fold direction itself is linked to in another expression as wel (to make the back of the page).

When i drag the point control in my external comp everything works fine. When i add a keyframe to the point control the fold direction no longer follows the point control.

Hope that explains the issue ?

Thanks !

comp("Imac_image_new").layer("citypath-pass-2").effect("FOLD")("Point")

Thanks a lot ! That worked !

Now i'll try to figure out how you wrote that :)
