problems with <xsl:variable>

 
Hi there
 
I'm struggling to understand why the evaluation
test=<"string-length($variable_name)" evaluates to 0, when the output I get
for the same variable (when calling it in <xsl:value-of select="$
variable_name"/> is 1006410 (i.e. NOT 0 in string-length!)
 
Below is a portion of my code in context :
 
<xsl:variable name="origID">
              <xsl:value-of
Select="Statements/ClientStatements/StmtsClient/Client/original/ID"/>a
</xsl:variable>
<xsl:variable name="copyID">
              <xsl:value-of
select="Statements/ClientStatements/StmtsClient/Client/copy/ID"/>
</xsl:variable>
 
 
<xsl:choose>
 
<!--   WHY WON'T THE CHECK BELOW EVALUATE CORRECTLY WHEN USING
              VARIABLES origID AND copyID INSTEAD OF FULLY QUALIFIED NAMES
???
              IE : string-length(copyID) EVALUATES TO ZERO WHEN copyID
ITSELF EVALUATED TO "1006410"
-->
 
<xsl:when test="(string-length(origID) = 0) and (string-length(copyID) =
0)">
              <xsl:for-each
select="Statements/ClientStatements/StmtsClient/Client/Address/*">
                     <fo:block text-align="left" font-family="Garamond"
font-size="8pt" font-weight="normal">
                            <xsl:value-of select="."/>
                     </fo:block>
              </xsl:for-each>
</xsl:when>
 
 
Any help would be highly appreciated.
Many Thanks
