using the ID tag in a <TD>

I've been trying to use the ID= tags inside the <TD id=myName> ones so i can place text from a database on the table, but not using a text/input box. I want to be able to use the document.form1.myName.insertAdjacentText() option, but whenever i try to reference something with the id tag, it comes up with an error saying it doesnt recognise the object or it is null

Does any one know of a better way to insert text from a database into a table not using textarea/text boxes?

Thanks

might want to do

<td><div id="MyName">blah blah blah</div></td>

instead...

then you can say:
document.getElementById("MyName").innerHTML = 'this text';

actually, that'd probably should work with

<td id="MyName">blah blah blah</td>

as well

and if you need to append new text then:
document.getElementById("MyName").innerHTML += 'this text';
