Help with disabling continue button! (case 22218)

[atran]

Hi Jason,

I am having an issue with presentation of a page on Medialab. Basically what I want to do is have participants hear an audio file (using backsound) while selecting a multiple scale response. However I want them to listen to the full audio before moving on and selecting their choice. For some reason using the d-60 parameter won't disable the continue button. So participants are able to select an item and skip ahead before the audio is complete. Any help you could give me would be great!

Thanks

Alex
