Help in AS - Display ads

Hello guys,

I need your help in resolving my issue. Attached herewith is the FLA and SWF of an online ad im trying to build.

Here's what I want to achieve:

• When user clicks on "Start Now" button, 3 survey templates animates with intervals set to 4 seconds each. I managed to do that.
• Now my client wants a feature wherein if the user tries starts to interact with the ad by using the scrollbars on the survey template, the setInterval code at 4 secs stops,
• then when the user stops scrolling (onRelease), it will trigger a 1.5 secs interval before going to the next template.

I have tried the best of my knowledge to fix it but to not avail. I hope this forum can help.
AS2 only please.

Thanks in Advance.
