how to pass parameters down through nested templates u

Peter, I am using the MatrixXML(attached below) to Table Creation
template you posted here to help me out.

Other than that one below I am using a number of templates that call on
others using  <xsl:apply-templates select="abcd" mode = "xyz">

But now I need to add something to it. Parameter passing down the nested
apply-templates to have a penetration of the "parameter" values as far
as I choose using further <xsl:with-params... > and also be able to
choose/between and modify values or send the original parameters the
template was called with further down to the templates that would be
called by the current template.

An example of that is in the code below. Of course it does not work.

At the first instance it sees this
"<xsl:with-param name="HeadAlign" select="{$HeadAlign}"/>"
It says
"Invalid XPath Expression"

While this works:
<xsl:with-param name="HeadAlign" select="Left"/>

Now I am curious if there is a way to pass that Incoming Parameter down
to the next templates as my outgoing parameter?

If I can use a "local" variable to store the incoming parameter and then
output it, then how can I do that? Please show me with a small code
sample.

I appreciate all your help. If you do know a way or have any ideas or a
web link for tutorial/discussion that will help me do so please let me
know.

Thanks,

Abhishek
