It looks like your input data has a blank cell somewhere, which you are
trying to convert to a number. 

Since you're using XSLT 2.0, I would recommend (a) using functions rather
than named templates, and (b) declaring the types of your variables and
parameters (for example as="xs:integer"). This makes this kind of user error
much easier to diagnose.
