I would like to trigger a timeline animation in Unreal engine which for example scales a cube. So I have most of the puzzle figured out thanks to Richard but was wondering how to send an integer to unreal as a variable so I can use that variable to set a percentage value dynamically for the cube to animate it a certain amount dynamically (EG: dynamic bar graphs or infographics).

The end goal is to build a web interface that our studio operators can use to trigger events in unreal but currently on day 2 of learning Aximmetry so sorry if this is a Newbie question I did search the forums first.
