trigger animation in adobe animate from php

I want to force a gotoAndPlay('dopeMovieclip') action based on a PHP variable I pass to the HTML page from the query string.

I don't need help with the PHP>>> 😉
but I am not sure (nor can I find anything out there) that explains how to do this in the simplest format.

Basically, I am not sure how to assign/call a variable properly that can be called from the published HTML page AND I am not sure how to call that variable from my HTML Source.

thx in advance 😉
