RE: RE: [xsl] Setting values for variable

[cknell@xxxxxxxxxx]

Of course, you are correct. pterm1 is out of scope when I tried to access its value. I took my eye off the ball for a second. Nevertheless, you can't change the value of a variable once it has been set. You'll have to stop thinking that XSL is another programming language like C, or Java or Perl or BASIC. You'll need to provide a broader context, more information, before anyone can help you solve the problem. How do you plan to use the value outside the <xsl:for-each>? 

I have often found that the <xsl:for-each> is used by people new to XSLT (this was true of me when I first started) in situations where <xsl:apply-templates> is more appropriate simply because the for-each-next loop is such a familiar programming construct.

It's not working.
First of all, if you do it like that, it will generate error, since pterm1 
is out of scope (pterm1 is inside for-each and inside a when)
Secondly, If I place the declaration of pterm1 outside the for-each, as 
follow:
<xsl:variable name="pterm" select="0"/>
<xsl:variable name="pterm1">
<xsl:for-each select="$lstAccount[Account_Type=$grpRecord]">
<xsl:choose>
<xsl:when test="string-length(normalize-space(Payment))!=0">
<xsl:value-of select="$pterm + Payment"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$pterm + 0.02*Balance"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:variable>
<xsl:value-of select="$pterm1"/>

The calculation is not correct.
Any other ideas out there ?

Thanks
