Wendell, Just made the changes you suggested. But still have an issue. Please correct the following if they are wrong. To push the initial value of the parameter - (Okay or not) <xsl:with-param name="HeadAlign" select="'Center'"/> <xsl:with-param name="DataAlign" select="'Left'"/> To obtain the parameter value in the called template (with default values) <xsl:param name="HeadAlign" select="'Right'"/> Its just a literal string that I want to place in the <th>, <td> or <tr> tags to set the text alignment of the cell. Like this... (doesn't work) To push the value of the parameter out. (Should I use XSL"value of and how would I actually write it into the the following HTML tags ?? <tr align="$HeadAlign"> <th align="$HeadAlign"> <td align="$DataAlign"> Unfortunately it wont "spit" out those parameters into the th, tr, td values. I have tried this with curly braces and without and etc. Of course I am getting nowhere with the trial and error. Please let me know what would be the correct "syntax" for the THREE XSL statements as mentioned above. (to make this possible :( ). Thanks a lot.

Abhishek, At 05:08 PM 9/10/2003, you wrote: >At the first instance it sees this >"<xsl:with-param name="HeadAlign" select="{$HeadAlign}"/>" >It says >"Invalid XPath Expression" Yes, that'll break. Correct would be select="$HeadAlign". >While this works: ><xsl:with-param name="HeadAlign" select="Left"/> "Left" is a valid XPath expression: it's short for child::Left (element children of the context node named "Left"). That might not be what you mean it to be, but it won't throw an error, either. To bind the string literal "Left" to the parameter, use select="'Left'".
