Default Create a semi-colon delimited value

Hello,
  I need to create the default "value" attribute for the select box depending on which option values are "selected". So far I can get value=13. What I need is value=1;3. All I need to do is add a semi-colon after the first one. I just don't know how to do that when you can't use counters in XSLT.

 My input is as follows:
<select multiple="true" name="test" >
 <option value="1" selected="selected">one</option>
 <option value="2">two</option>
 <option value="3" selected="selected">three</option>
 <option value="4">four</option>
</select>

Here's my code:
<xsl:choose>
   <xsl:when test="@multiple">
        <xsl:attribute name="value">
          <xsl:for-each select="option[@value and attribute::selected]/@value">
               <xsl:choose>
                       <xsl:when test="$counter &gt 1"></xsl:when>
               <xsl:otherwise>;</xsl:otherwise>
                   </xsl:choose>
                   <xsl:value-of select="."/>
              </xsl:for-each>
       </xsl:attribute>
      </xsl:when>
   <xsl:otherwise>

      <xsl:attribute name="value">
    <xsl:value-of select="option[@value and attribute::selected]/@value"/>
      </xsl:attribute>
   </xsl:otherwise>
 </xsl:choose>
Thanks,
Ralph

Default

If you want a semi-colon delimited list of all selected options you need:
Code:
<xsl:for-each select="option[@value and @selected]">
<xsl:value-of select="@value"/>
<xsl:if test="position() != last()">;</xsl:if>
</xsl:for-each>
I can't see the need for the @multiple test; this only tests for the existence of the attribute by the way, not if it is set to true.
