Receiving "Transform" key value from level sequence in Blueprint

Hi All!
I am trying to make a blueprint to change character’s facial texture map as time track goes.
To make this, I set key values to the Tramsform-X in the other section.
Can I get the Transform-X value in a specific frame to transfer it to a parm in a certain material?
I’ve made the draft of blueprint, but i am stuck after “Get Key(double)” node. I can’t get any valur that I expected.
Please help me.

This should work.
You can filter out specific channel based on its name, e.g. Location.X, Location.Y etc.
