How do I make the customized HTML "Continue" button work? (case 3800)

[chunnjh94]

I was trying to show both the HTML file and a scale response with radio buttons on the same screen. I created a text file that contains a question, an image and some radio buttons, and a "Continue" button, and then saved it as a an HTML file. I selected the item type as a "custom item", and I attached the HTML file under file name. I was able to use MediaLab to display the HTML file, however, the radio button response was not being recorded, and when I clicked on the continue button, nothing happened (it didn't take me to the next screen). How do I correct these problems??
