Automation Blocks - Get Value and Expression It

Question

I've been doing so much file management stuff, I've not yet dived too far into layer stuff yet. So, I thought I'd start of simple, and very quickly got lost.

I find myself accidentally grabbing layers and moving them and have found that expressing them to a position works really well when working.

I am unable to figure out how to "get" a value of a selected layer and then express that value into the position field.

How do I turn this...

Into this?

I know how to "set" the expression via a block, but not how to poll the Position value into a variable so I can apply it, but this ain't it.

As always, any input is appreciated.

I think the issue is the "without root" option of your "get attribute value" block.

You need to choose a root layer there from which the position should be taken.

I just did this quick test, which "expresses" all selected properties:

Technical detail: Note that "my value" is a list and when using it for setting the expression, it is converted into a text of the form "[val1,val2,val3]" automatically, which is the correct syntax you need in expressions.
