I am building an HTML launch page and I'm running into some problems.

I have four paramters total. 3 of them are static parameters that will be selected via drop down or radial button.

The fourth paramter will be a dynamic edit box. The 3 static parameters need to be passed to the fourth so the values are paired down to whats available based on the controls. I looked at documentation and I thought I had the chaining arrows hooked up right but I get an arrow message saying there was a problem chaining when I launch the web page. Does anyone no how to complete this behavior?

The best way to do this, imho, is to place all four values in a hierarchical file and read that file for each of the controls and chain the controls together.

Or, place all the combination of the first three values in a file which is joined to the 4th file which is dynamic, and filter the 4th control accordingly.

If you're willing to edit the XML in the HTML page, let me know and I can give you a quick run-down. If you're not familiar with HTML and XML, you might not want to mess with it. I've had to that at times to deal with this error. . .

Rob - I'm working on an upgrade from 8.0.08 to 8.2.03 and getting an alert on a few pages that "There appears to be an issue chaining 'A' to 'B'. Can you please post some details about what you updated to resolve this issue? We've already had to make manual edits to these pages for a variety of reasons.

Hi juram,

It's been a bit since I had to do one of these! It will be a couple days, but I'll try to get back to you. Here are a couple things quickly:

Make sure it has exactly one rootxmlnode tag.
Make sure the requests_list tag values correspond to valid requestid values in a request tag.

Each html_element that is part of the chain should have a link tag defining it's data source. The second html_element's link tag should have a "from" attribute referencing it's parent html_element, and the second html_element should have two link tags, referencing the previous two elements in the chain. As I recall!
