};

function makeATable()
{ var n = 1;
counter = parseInt( document.form1.txt1.value );
var tcounter = document.getElementsByTagName('table');
m = tcounter.length + 1;
if ( m >= 9 || counter == 0 ) { return false; }
div = document.getElementsByTagName('div');
do
{
var table = document.createElement('table');
for ( var i = 0; i <= n; i++ ) { var tr = document.createElement('tr');
for ( var j = 0; j <= n; j++ ) {
var td = document.createElement('td');
var celtxt = document.createTextNode('Table ' + ( n * m ) + ' Row ' + ( i+1 ) + ' Column ' + ( j+1 ) );
td.appendChild( celtxt );
tr.appendChild( td ); }
table.appendChild( tr ); }
div[0].appendChild( table );
n++; }
while( n <= counter );
form1.btn1.onclick = function() { for ( var x = 0; x < tcounter.length; x++ ) { div[0].removeChild(tcounter[x]) }

Yes i believed that theres a better way to do this! But its up to you which pattern you wil take. And as much as possible i always want to provide examples' rather than giving reference or any guide related to the issue! And not to mention that i am only using nokia6600 with mobile browser opera 8.65version on editing and testing every code, so that's 1 part of the problem due to the browser capabilities. So hope you wil understand if sometimes my codes dont give precise results. Wel as we go back to
the issue, this code has been updated! And about ui validation am stil workin on it!

Even if you know there is a better method out there which doesn't end up reinventing the wheel?

Oh, so you prefer zombie feeding? BTDT. This way of helping not only makes the posters depend on ready solutions but also hinders their thinking process. Nowhere in the entire post the poster has made an attempt to solve the problem at hand but still has got hold of enough code.
IMO, helping out by churning code snippets is easy; forcing the poster to learn and think isn't. Let your answers create people who can pass along the knowledge rather than ready code.
