F4V video will does autoplay but won't show with autoplay "false"

I’ve developed a form application using screens for a portfolio. On one screen, is a multimedia (video) piece that appears on “stage” once visitors click the “multimedia” text button. The screen appears fine and the video shows with the parameter to autoplay toggled to “true.” However, as this is just one of many screens, I only want it to play when the screen loads or when the visitor clicks the play button.

I’m sure it’s something small that I’ve missed. Has anyone else run into this or know why this happens or what I may’ve missed? Am grateful for any helpful assistance anyone offers.

Thanks.

P.S. Excuse the bad grammar in the thread title.
