XML/XSLT nested list

[Rich75]

I have a nested list structure but the bullet point for the first nested item has an idented bullet like I want it too, but it also has another bullet that's not idented like the outer list. I can't figure out what I'm doing wrong. This is my code. If you could help that would be great.

 XML:

<MAIN>
<MSA>
    <MSA_DESC>
      outer item
    </MSA_DESC>
  </MSA>

  <MSA>
    <MSA_DESC_SUB>
      <SUB>
        <SUB1_VALUE>
          inner item
        </SUB1_VALUE>
      </SUB>
    </MSA_DESC_SUB>
  </MSA>
</MAIN>

XSLT:

<span>
                  <ul>
                    <xsl:for-each select="MAIN/MSA">
                      <li>
                        <xsl:value-of select="MSA_DESC"/>
                        <ul>
                          <xsl:for-each select="MSA_DESC_SUB/SUB">
                            <li>
                              <xsl:value-of select="SUB1_VALUE"/>
                            </li>
                          </xsl:for-each>
                        </ul>
                      </li>
                    </xsl:for-each>
                  </ul>
                </span>

It's displaying like this:

* outer item
* * inner item

with the extra bullet on the inner item that I don't want.

I figured out the dilemma in my previous post. This is what the xml and xslt should look like:

XML:

<MAIN>
<MSA>
      <!-- First Outer Item -->
      <MSA_DESC>this is first outer bullet text</MSA_DESC>

     <!-- First Inner Item -->
     <MSA_DESC_SUB>
     <SUB1_VALUE>this is first inner bullet text</SUB1_VALUE>
     </MSA_DESC_SUB>

     <!-- Second Inner Item -->
     <MSA_DESC_SUB>
     <SUB1_VALUE>this is second inner bullet text</SUB1_VALUE>
     </MSA_DESC_SUB>

</MSA>

<MSA>
         <!-- Second Outer Item -->
          <MSA_DESC>this is second outer bullet text</MSA_DESC>
</MSA>
</MAIN>

XSLT

<span>
                  <ul>
                    <xsl:for-each select="MAIN/MSA">
                      <li>
                        <xsl:value-of select="MSA_DESC"/>
                        <ul>
                          <xsl:for-each select="MSA_DESC_SUB">
                            <li>
                              <xsl:value-of select="SUB1_VALUE"/>
                            </li>
                          </xsl:for-each>
                        </ul>
                      </li>
                    </xsl:for-each>
                  </ul>
                </span>
