Please give the attached form a try. The important parts are the conditional formatting on the second repeating table, and the formula in the Calculated Value box in the Value column.

It sounds like the rule isn't working. Where did you place the rule exactly? Is it on the MSLB's group, or on the repeating field? It should be placed on the repeating field.

Just to make sure, could you attach a screenshot of your source and destination data source?

Could you clearly describe what it is you want to do? It's not clear from your post or from your example.

How about something like this:     While (xiPreviousProductDescriptions.MoveNext())        Dim prevSkuNode as XPathNavigator = xiPreviousProductDescriptions.Current.SelectSingleNode("@SKU", ns)        If prevSkuNode IsNot ...

Try this:      myEnvelope.Subject = CreateNavigator().SelectSingleNode("/dfs:myFields/dfs:dataFields/d:tblConferenceDetails/@CONFTitle", NamespaceManager).Value

Forgive my ignorance, but what is a transparent black background? Is this a browser form or a filler form?

Do you know how the line breaks are actually stored in the list? Whether they are stored as <br />s or as newline characters?

I believe we have encountered this behavior when the person publishing the form is not a site collection administrator. Could you ensure that the person publishing the form is a site collection admin?

I suggest trying this:     sum((firstField | secondField | thirdField | ...)[number(.) = number(.)])
