scrollstart function

[lynnkeen]

I have been working on a problem for many days that I can't seem to determine the source of the error. We have an image slideshow scroller which has the employee's photo with their name as a hyperlink under the image. The javascript used to create this is the dynamic drive up-down image slideshow script with a minor cold fusion output query which grabs the newest (within 30 days) employees and shows only those.

The scroller worked up until a day or so ago. There were no updates to the server with respect to IE, or SP packets. After a review of the script I see that the process calls for a scrollstart function.

<script language="JavaScript">
<!--
function startscroll(){ return true}
//-->
</script>

I made sure this was in my main page as the code indicates that it looks to the main page to launch. But I was wondering if there's another .js file that I might need to update. Can anyone give me any clues to search for?

Thanks!
Lynn

Warning: Please include a link to the DD script in question in your post. See this thread for the proper posting format for asking a question.

It's hard to say without seeing the source of your page, though function startscroll() is a lot longer than what you've posted. See here: http://www.dynamicdrive.com/dynamici...nslide_dev.htm There aren't any .js files referenced by this script.

My apologies...it was an omission on my part. The updown slideshow scroller is the one I'm using and the page is part of an 'include' within my main page. It looks like this:

<CFINCLUDE TEMPLATE="/Common/nocache.cfm">

<CFPARAM Name="Counter" Default=0>
<!---get new emp list--->

<CFQUERY NAME="Start_list" DATASOURCE="#CALWebDataSource#">
SELECT EMP_NO, LAST_NAME, FIRST_NAME, NICK_NAME, START_DT, DIRECTORATE, CATEGORY, Location, EMPPHOTO
FROM Employ
WHERE (STATUS = 'Active') AND (START_DT > DATEADD(m, - 1, GETDATE()))
ORDER BY START_DT DESC
</CFQUERY>

Well, some of the above code is dynamically generated, so without seeing the final output, it's impossible to say where the problem lies. If you have a link to the actual page using this script, please post it.
