[xsl] XSL variable out of scope

[Nischal Muthana <nischal_muthana@xxxxxxxxx>]

Hi All,

I have an xml and xsl like the following. When I apply
the xsl I need to get the following HTML

Home: 4089888888
Business: 40888888

But I get an error saying variable out of scope. And I
know I am using a variable declared in a different
scope. I am kinda stuck here and I dont have any more
ideas to counter this. Can someone help me find a way
to tackle this problem. 

PhoneList.xml

<?xml-stylesheet type="text/xsl"
href="C:\TestXSLT\xsl\PhoneList.xsl"?>
<PhoneList>
	<Phone>
		<PhoneUseCode>BUS</PhoneUseCode>
		<PhoneNumber>4082389033</PhoneNumber>
	</Phone>
	<Phone>
		<PhoneUseCode>HOME</PhoneUseCode>
		<PhoneNumber>4082834798</PhoneNumber>
	</Phone>
</PhoneList>


PhoneList.xsl

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:template match="/">
<xsl:for-each select="//PhoneList/Phone">
	<xsl:variable name="PhUseCode"
select="PhoneUseCode"/>
	<xsl:choose>
		<xsl:when test="$PhUseCode='HOME'">
<xsl:variable name="HomePhone" select="PhoneNumber"/>
	</xsl:when>
	<xsl:when test="$PhUseCode='BUS'">
<xsl:variable name="BusPhone" select="PhoneNumber"/>
	</xsl:when>
</xsl:choose>
</xsl:for-each>
<tr>
	<td>&#160;</td><td>&#160;</td>
	<td nowrap="nowrap"
colspan="2">&#160;&#160;&#160;Home</td>
				<td nowrap="nowrap">"<xsl:value-of
select="$HomePhone"/></td>
			</tr>
			<tr>
				<td>&#160;</td>
				<td>&#160;</td>
				<td nowrap="nowrap"
colspan="2">&#160;&#160;&#160;Business</td>
				<td nowrap="nowrap"><xsl:value-of
select="$BusPhone"/></td>
			</tr>
	</xsl:template>
</xsl:stylesheet>
