Biztalk Mapper XSLT Compile Error

Question

I'm mapping relationship data based on a type Mother/Father etc. when extracting the data from a table looping functoid and checking for a type of Father, Mother etc. I am getting the following error:

XSL transform error:. XSLT compile error at (1220,45). See InnerException for details. 'userCSharp:LogicalEq(string($var:) , "FATHER")' is an invalid XPath expression. 'userCSharp:LogicalEq(string($var:) , "FATHER")' has an invalid qualified name.

Source extract example

<relationships>
   <RelationshipType>Father</RelationshipType>
   <Details>
      <Title>MR</Title>
      <Fullname>Surname, forename</Fullname>
      <etc...>
   </Details>
</relationships>

It's appears that the compiler is missing the $var:XXX value, it is unclear on how this is missing presently as this is system generated. Any ideas on how to track this back to the map?

Just to update, issue is now resolved.

Visual Studio issue seemed to be linked with a tabel looping functoid, needed to remove the functoid and links before re-adding to resolve the issue.
