Table Cells Acting Weird

This must have a simple solution!

Alright, I haven't done any coding in a loooong while haha...the answer probably is staring me in the face, but I can't for the life of me figure out why this isn't working.

<table class="mine" cellpadding="0" cellspacing="0" border="0">
<tr>
<td class="leftbar" rowspan="5" height="800" width="17"><img src="/Test/LeftBar.jpg"></td>
<td class="header" height="111" width="900"><img src="/Test/Header.jpg"></td>
<td class="rightbar" rowspan="5" height="800" width="17"><img src="/Test/RightBar.jpg"></td>
</tr>
<td height="18" width="900"><img src="/Test/NavBar.jpg"><img src="/Test/NavUpdates.jpg"><img src="/Test/NavArtwork.jpg"><img src="/Test/NavTutorials.jpg"><img src="/Test/NavAbout.jpg"><img src="/Test/NavContact.jpg"><img src="/Test/NavLinks.jpg"></td>
</tr>
<tr>
<td height="399" width="900"><img src="/Test/MainSmall.jpg"></td>
</tr>
<tr>
<td align="left" height="174" width="299"><img src="/Test/Updates.jpg"><img src="/Test/TextBox.jpg"></td>
</tr>
<tr>
<td height="98" width="900"><img src="/Test/Footer.jpg"></td>
</tr>
</table>

Now in the row that contains the "Updates" and "Textbox" images...I currently have 2 images there. I want to replace them with two table cells (that will contain these images. The TextBox image will be the background for the right cell). Simple enough, right?...the TextBox cell keeps getting pushed out to the left though, every time I add it.

Any assistance would be greatly appreciated, and I'm sure I'll give myself a facepalm later. Thanks :)

<tr> missing on the 7th line.
You need to set the colspan=3 for the other tds'.

i use the same validator with the Web Developer firefox add-on.
