I feel like we're so close I can TASTE it..arrrgh..

I adjusted yours slightly to work with my page thus:
----
function addDoctor(name, city, id)
{
  var docTarget = window.frames['docs'].document;
  var myTable = docTarget.getElementById('mydocs');
  var myTableBody = docTarget.createElement("TBODY");
  var newRow = docTarget.createElement("TR");
  var newCell = docTarget.createElement("TD");
  var newText = docTarget.createTextNode('someText');
  newCell.appendChild(newText);
  newRow.appendChild(newCell);
  docTarget.getElementById(myTableBody).appendChild(newRow);
}
----
Remember, I am using a page with iframes and this is called from one
of the iframes. I tried changing window.frames to parent.frames with
no effect.

This essentially gives me an error on the last line - getElementById
is NULL or not an object.

I don't fully understand the table body thing anyway - maybe this is
the problem. Should I just PUT a <tbody> tag in my table first? Do I
need that..why doesn't it see the table body?
