Trouble with diving column items correctly

I am trying to divide the items between 3 columns evenly and leave the remainder in the 3rd column.   However my code below keeps putting the last item back into the first column.   If you want to see what's happening, go to www.medicouponmanager.com and check out the bottom of the "select your health condition" section.  The last item is put back into the first column for some reason.  I want it to stay in the last.  

My code is below.   How can I fix this so that it ends up in the last column?
writer.WriteBeginTag("ul")
                If isRoot Then
                    writer.WriteAttribute("class", "KartrisMenu")
                Else
                    writer.WriteAttribute("class", "KartrisSubMenu")
                End If
                writer.Write(HtmlTextWriter.TagRightChar)
                writer.Indent += 1

                For Each item As MenuItem In items
                	intCounter += 1
                    BuildItem(item, writer)


If intCounter = Cint(items.Count/3) And intCounter >= Cint((items.Count/3)-1) then
	writer.Write("</ul><ul class=""KartrisMenu hide_me"">")
	intCounter = 0
End if

                Next

                writer.Indent -= 1
                writer.WriteLine()
                writer.WriteEndTag("ul")
            End If

Your last item ("Yeast Infections") is being put into a ul of its own.

<li class="KartrisMenu-Leaf">

                        <a href="/Womens-Health__c-p-0-0-75.aspx" class="KartrisMenu-Link">
                              Women's Health</a>
                  </li></ul><ul class="KartrisMenu hide_me">
                  <li class="KartrisMenu-Leaf">
                        <a href="/Yeast-Infections__c-p-0-0-70.aspx" class="KartrisMenu-Link">
                              Yeast Infections</a>
                  </li>
            </ul>


It's because of this statement:

If intCounter = Cint(items.Count/3) And intCounter >= Cint((items.Count/3)-1) then
      writer.Write("</ul><ul class=""KartrisMenu hide_me"">")
      intCounter = 0
End if

You have 73 items. If you divide by 3, you get 24 with a remainder of 1. You don't have any code to otherwise deal with this remainder so it is being put into a new ul. There's no more room for a fourth column of list items on the page, so it's being put at the bottom left, thus it appears to be at the bottom of the first column.

I think it would look nicer if the extra list item was in the first column. I would do this. Outside your loop, create a boolean value, Dim firstColumn As Boolean=true and a variable that holds the items.Count, Dim allItems As Integer = items.Count. Then change this statement to:

If firstColumn then
        If intCounter = allItems + (allItems Mod 3) Then
            writer.Write("</ul><ul class=""KartrisMenu hide_me"">")
              firstColumn = false
              intCounter = 0
        End If
else
        If intCounter = allItems/3 Then
            writer.Write("</ul><ul class=""KartrisMenu hide_me"">")
            intCounter = 0
        End If
End if
