You can't put elements (eg. xsl:value-of) inside of an attribute.. in this case
the test attribute of the element xsl:if.

But, don't worry! because there is an easier way to get at that value.

When you say "setup" is the "name" of the checkbox.. I will assume you mean the
text that resides beside it since that is what it appears you are trying to do.

This should work :
<p align="center">
   <xsl:value-of select="strValue"/>
   <xsl:if test="@textValue='Y'">  <!-- checked -->
           <input type="checkbox" align="center" checked="Y" value="Y"/>
   </xsl:if>
   <xsl:if test="not(@textValue='Y')">  <!-- not checked -->
           <input type="checkbox" align="center" value="Y"/>
   </xsl:if>
</p>

I don't know if you still wanted the value of the checkbox etc to be the same in
each case.. but the general structure is there. Notice I extracted the
duplicated sections and just put them once on the outside of the xsl:if
sections. You could even reduce further by just adding an attribute named
checked="" in the case where it should be checked. But maybe that is getting
silly =)

Note.. the above DOES assume that it is being executed while within the option
node... that is, within an <xsl:apply-template select="option"> or something
similar.

You could also just use xsl:choose like this :

<p align="center">
   <xsl:value-of select="strValue"/>
   <xsl:choose>
      <xsl:when test="@textValue='Y'">  <!-- checked -->
          <input type="checkbox" align="center" checked="Y" value="Y"/>
      </xsl:when>
      <xsl:otherwise>  <!-- not checked -->
           <input type="checkbox" align="center" value="Y"/>
      </xsl:otherwise>
   </xsl:choose>
</p>


And although a little wordier... it does seem clearer to me what is going on.

Good luck.
