HTML5 text entry box variable doesn't update

Hello all- so when I create a text entry box in Captivate 6, associate a user variable with the TEB, the variable updates fine when I preview in browser. Whatever I type in the text box automatically updates the variable as expected. But when I preview as HTML5 Output, the variable doesn't update. I need to capture user input in a text entry box and publish using HTML5, is there something I am missing to utilize TEB input when publishing to HTML5?

Thanks in advance to anyone who can help!!
