That solved it.  Now I've got another problem, though.

I've got a new template that takes a parameter and returns a formatted
version of that parameter.  No problems there.

I'm trying to rewrite another template to be able to be called regardless of
what entity is currently matched.  The two templates in question are below.
(The various '???Mod' templates are identical except the ??? part is
replaced throughout.  Any place with '...' denotes a bulk of
non-problematic, or essentially identical code removed for clarity's sake.)

- - - - -

<xsl:template name="strMod">
	<xsl:variable name="str" select="abilities/@str"/>
	<xsl:variable name="mod" select="($str div 2) - 5"/>
	<xsl:value-of select="round($mod - .5)"/>

<xsl:template name="abilityMod">
	<xsl:variable name="ability"/>
	<xsl:variable name="up" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
	<xsl:variable name="lo" select="'abcdefghijklmnopqrstuvwxyz'"/>
	<xsl:if test="translate($ability,$up,$lo)='str'"><xsl:call-template

- - - - -

Excerpt from MUCH larger stylesheet.
- - - - -

	<xsl:for-each select="skills/skill">
		<td class="borderbottom" valign="bottom" align="middle"
			<font style="FONT-SIZE: 8pt">
				<xsl:call-template name="formatMod">
					<xsl:with-param name="mod">
<xsl:value-of select="@ability"/>

- - - - -

The pertinant xml looks something like this:
- - - - -

<DD3e-character attributes="...">
	<abilities str="18" dex="13" con="15" int="6" wis="7" cha="11"/>
		<skill name="Run" ranks="4" ability="STR"
uri="../skill/run.xml"/>	</skills>

- - - - -

The 'strMod' template works fine if the last match was 'DD3e-character', but
I'm in the midst of an <xsl:for-each select='skills/skill'>, and I need to
do an <xsl:call-template name="strMod"/> which doesn't return a darned thing
at that point.  What's the syntax for an absolute path from the root node?

It's hard to tell, since you don't provide your implementation of the
template conMod, but it looks like it's returning the string '+2'.

If that's the case, '+2' cannot be converted to a number, as there is no
unary + operator in XPath. Thus, it's converted to NaN and the result of
any numeric operation with NaN is always NaN.
