Rob just wanted to thank you for your reply and making me understand exactly the error in the way I was understanding how the for-each works. This fixed my problem. Once again thanks for the prompt reply. John M.

Just so you know (you say you are new) - when using a value-of and the thing you are trying to access doesn't exists, it will return null as opposed to an error. > ***<xsl:value-of select="employee"/> --- Value is John > Doe *********** at this point you could set <xsl:variable name="sKeeper" select="employee" /> > <select name="employee"> > <xsl:for-each select="$v_employer/employer/option"> > > ***<xsl:value-of select="employee"/> --- Value is empty When you use the for-each you are moved into that part of the tree. Meaning everything is relative to the point $v_employer/employer/option. Is there an employee element like $v_employer/employer/option/employee? if not that is why it is null. > *********** if you use that variable comment above you could do something like <xsl:if test="string($sKeeper) = string(.)"> etc etc > <xsl:if test="employee= '{.}"> > <option value="{.}" > selected="selected"><xsl:value-of > select="./description"/></option> > </xsl:if> > <xsl:if test="not(employee= '{.}')"> > <option value="{.}" "><xsl:value-of > select="./description"/></option> > </xsl:if> > </xsl:for-each> > </select> > > I guess my question is can this be done or how can I > bring a value from the > main template in to be compared to the item on the list > as it is iterating > through it. I think you were just missing the fact that your context moves.
