Ok here goes,

I have a javascript which creates rows in a table based on form entries which works with no problem, now I need to delete rows but I can only seem to delete the first and last row in the table!  

is there some way to set the row "id" and delete rows based on that id?

Also if you havppen to have a link to a tutorial on string and array manipulation I would appreciate it as I need to do things in javascript I do in perl like push, pop, split, join, .=, etc...

String functions can be found here

you can hide rows in table with
document.getElementById(<tableid>).rows
[<rownum>].style.visibility="hidden";

Here the remove row code:

<html>
<head>
<script>
function delRow(theButton){
  theTab = document.getElementsByTagName('table')[0].firstChild;
  rNum = theButton.form.rowNum.value;
  theTab.rows[rNum].removeNode();
}
</script>
</head>
<body>
<form>
<input type=text name="rowNum" size="1">
<input type=button value="Del" onClick="delRow(this)">
</form>
<table border="1">
<tr><td>0</td></tr>
<tr><td>1</td></tr>
<tr><td>2</td></tr>
<tr><td>3</td></tr>
<tr><td>4</td></tr>
<tr><td>0</td></tr>
</table>
</body>
</html>
