Problem with RTF Output for Custom Tagged Value

[AlanT]

   I am using EA 8, latest build.  I have created a UML profile that extends the Requirement class, and I added a Tagged Value called DocImpact.  DocImpact is an enumerated field with the possible values of Yes or No.  

    When I generate a report that should print this value in the third column of a table, I get instead the RTF Template tag string, like this:

{Element.valueOf(DocImpact)[ch1917]

on many of the entries.  Others are blank.  

My RTF template has the following in it:

Req. ID      Requirement Text      Documentation Impact?
package >element >
{Element.Name}      {Element.Notes}      {Element.Tag}{Element.valueOf(DocImpact)}
child elements >
< child elements
< element

child packages >
< child packages
< package

       Anyone know what is going wrong here?        

                     Thanks, Alan
