I outputted the value of the @ and variable to another variable and in both cases it contains a value. Then when I do the same but also add the called template to the sequence and cast the variable or @ as xs:integer the process fails and outputs the error message. I've now added a test if the @cols exists and it runs in the first instance but not in the second. But after David suggested using xs:integer(@cols) everything worked fine. Is there something you were looking for in particular? MM Quoting Michael Kay <mike@xxxxxxxxxxxx>: > > I'm using Saxon 8, and get the following error msg: > > Fatal Error!
