Yes - That was the problem - the debugger did not show a value, so I assumed
the error was caused by that. And we know what happens when one assumes...
A variable that performed a calculation based on the values of the other
variables was failing. Rearranging my code to print out the variables pointed
me to a missing dollar sign deep in the expression.
Thanks!

What do you mean by saying that a variable has no value? How did you examine
the variable?
Variables in Saxon are often evaluated lazily (on first reference). If
you're using a debugger then it may be visible that a variable hasn't (yet)
been evaluated. But if you reference it from your code, it should always
have a value.

Subject: [xsl] Variables have no value
Good afternoon -
I'm using XSLT 2.0, Saxon8b, XEP4.4...
Some of my variables are initializing and some are not. I've
reordered them, overlaid non-working ones with working ones,
added new ones, renamed them and revalued them and the same
ones still won't initialize. I've googled and searched
through the 6 or 7 books on my desk and can't find a reason
why. What am I missing?
<xsl:template match="something">
<xsl:variable name="A11" select="number(10)" /> <!--
NO VALUE -->
<xsl:variable name="A21" select="number(4.5)"/> <!--
NO VALUE -->
<xsl:variable name="A12" select="number(313.6)" /> <!-- OK -->
<xsl:variable name="A22" select="number(208.1)"/> <!-- OK -->
<xsl:variable name="A32" select="number(6)"/> <!-- OK -->
<xsl:variable name="A42" select="number(6)"/> <!--
NO VALUE -->
<xsl:variable name="A52" select="number(6)"/> <!-- OK -->
<xsl:variable name="A62" select="number(6)"/> <!--
NO VALUE -->
<xsl:variable name="B32" select="number(43)"/> <!-- OK -->
<xsl:variable name="B42" select="number(22)"/> <!-- OK -->
<xsl:variable name="B52" select="number(3)"/> <!-- OK -->
<xsl:variable name="B62" select="number(3)"/> <!-- OK -->
<!-- Do something with the variables here. Fails with
Attribute 'x' cannot have a value of NaN error.--> </xsl:template>
Thanks!
