[xsl] Q - Value of param doesn't change !

[Ahsan Ali <doubleletter@xxxxxxxxx>]

For this code,

<xsl:call-template  name="JrnyTm">

<xsl:with-param name="hrs" select="number(format-number(JrnyTm div 60,
'#'))"/>
<xsl:with-param name="mins" select="JrnyTm -
(number(format-number(JrnyTm div 60, '#')) * 60)"/>
</xsl:call-template>

	<xsl:template name="JrnyTm" >
		<xsl:param name="hrs" />
		<xsl:param name="mins" />
		<xsl:value-of select="concat($hrs, ' hrs ', $mins, ' mins')"/>
	</xsl:template>


The call template code is inside a for-each element. So, ideally, it
should change its JrnyTm value everytime, right ? Well..it looks like
once the xsl:param [hrs] is set to 7, it stays that ! It looks as if
the select expression is not being evaluated for every element..

Any ideas ?
