Marker Animation Error
The plugin named "Flow" can create smooth animations with it's Bézier curve graph tool, by two ways: "Apply to Keys"or"Apply to Expression",the I choose the latter one, and apply to two position keys.After that, it create an expression like that:
Then I want to change all key. to marker. , so I can animate without keyframes,but by adding markers(shortcut : control+8 or "*"key on numpad).And now I have to add Point Controls that tells it move from here to there.
And it jumps an ERROR:
After Effects warning: Expression disabled. Error at line 1 in property ‘Position’ of layer 1 (‘MarkerAnimation’) in comp ‘MarkerAnimation’.
property or method named ‘thisProperty’ in Class ‘global’ is missing or does not exist. It may have been renamed, moved, deleted, or the name may have been mistyped.

It works, but why?
It might have worked if instead of this:
you used this:
BTW, I use the Expression pick whip (inserts a reference to target) to refer a point control , so it can't be a numerical value, but an array.
