Pin Not Working with Size Sine behavior

Greetings all!

Anyone know what I am missing? Trying to have four objects spin and shrink into a vortex pattern using the Pin behavior. Pinned to the parent gets the spin, but the position stays relative to the center of the parent. I wish to have the four objects stay relative to their location ON the parent thus getting them to spin into the center of the collapsing parent. Suggestions a greatly appreciated!

Try adjusting the Origin point of the green square to the far left. You will then have to rotate and re-position the green squares in the layout such that all their origin points are in the center of the larger vortex square. That should do it.

To be clear, when I say far left, I mean around -500 on the X value. The Y value can stay centered.

Awesome, David, thank you!
