RE:  Forgive the noob
There's no "up front" in XSLT: no after, no before, no concept of time at
all. It's a stateless language. Concepually, everything happens at once.
Accordingly, there's no concept of writing to a variable "at the start" and
reading it "later".

Your two <xsl:variable name="buyerfullname"/> instructions are declaring
completely unrelated variables, the only thing they have in common is that
they both have the same name.

Just do the initialisation within the declaration of the global variable:

<xsl:variable name="buyer"
> select="Contract/Borrowers/Borrower[NumOrder='1']"/>

<xsl:variable name="buyerfullname"
  select="fn:borrowerfullname($buyer)"/>

You could make that

<xsl:variable name="buyerfullname"
  select="if ($buyer) then fn:borrowerfullname($buyer) else ()"/>

but I would personally put the logic for that inside the function.
