Hi David, et al.
Yes, user picks a value on a "Select Value" form as a pop-up window in
a web page.
(You can see the sections of the .xsl file and the associated .xml
file at the bottom.)
Below is what the user is supposed to be doing and what's expected
(pretty straightforward)
1. User picks a building name using the Select Value form. Every
building is assigned an e-mail address back in the database, under
bl.wr_email
2. BAsed on the selected building, the "Send email to:" space
($toEmailAddress) on the main form is auto-populated by the
corresponding e-mail address of the building.
As seen in the .xsl, $toEmailAddress is included in the SelectValue
template to be able to pass a different value everytime the template
is called, and the XPath (called from within
temp_selectvalueform...xml) is
//dataSource/data/records/record[(_at_)bl(_dot_)wr_email]/@bl.wr_email)
What actually happens is even more straightforward: Nothing. The
$toEmailAddress param is not populated at all.
So, if someone could tell me (hopefully) specifically, what I may be
missing, that'd be great...
Thanks a lot..
Alp

<xsl:param name="actionTitle"/>
<xsl:param name="toEmailAddress"/>
<xsl:variable name="fmAction"

<xsl:if test="count($fmAction) > 0">
<input class="selectValue_AbActionButtonFormStdWidth" type="button"
title="{$fmAction/tip}" value="{$actionTitle}"
onclick='onSelectV("{$fmAction/@serialized}","{$recordName}","{$formName}");
selectedValueInputFormName="{$formName}" ;
selectValueInputFieldID="{$recordName}" ;'/>
</xsl:if>
</xsl:template>
Here's the XPath portion of the associated .xml file:

</database>

I am trying to assign a user-input value to a variable. I know that
variable values can not be changed within a given template, but I am
still not sure if what I am trying to do is possible or not? If it is
not, can xsl:param be an alternative, and how or is there another
alternative at all? Can this be done by templates?
what do you mean by "user-input value" ?
I am not at all sure, but I suspect that you mean a form on a web page?
If so you need to remember that XSLT just generates an HTML document, it
doesn't itself know anything about HTML. Once the HTML document is
created the XSLT process is _finished_ and the form is then passed to a
browser which interprets it as HTML and displays a form and accepts user
input. The prowser can then send the form data to whatever process is
handling the form, this may be another XSLT stylesheet but it's an
entirely different process from the one that generated the form
(although it could use the same stylesheet of course). If you want to
pass in values to a stylesheet then declare xsl:param at the top level
of the stylesheet and pass in the values when the stylesheet is
executed. There is a parallel thread on this list this week that
discusses various server and client side frameworks that allow such
parameters to be passed in.
