Thanks for the link. The HTML isnt really the problem its how to code this in PHP I am having difficulty

in. Can anyone advise on what i need to write on the server or point me in the direction of some sample

code?

Thanks

You don't show any <form> tags

Your <select>s don't have name attributes

You use PHP to output HTML code, but if you don't know the correct HTML, how do hope to get it right with PHP

Well that was taken straight from my lecture notes which I assumed to be correct.

Thanks for the observation!

Another copy and paste basically, i thought you said the HTML isn't a problem, if you don't it then it is. ?

No the PHP is the problem. It is my entention to write a more complex table as that only has 3 rows and columns but I merely wanted to gain an understanding in how to go about coding the PHP based on an easy table so I can apply the same principles to my own table

There is no way you can do anything in PHP from the HTML in your original post. I gave my reasons in my last post.

I use a form that takes the

# columns

# of rows

Border Width

Cellpadding

Cellspacing

and Table width

The php part then takes those inputs and creates the table using this,

print "<table border=\"$border\" cellpadding=\"$cp\" cellspacing=\"$cs\" width=\"$width$ms\">\n";
for ($r=0; $r<$row; $r++) {
     print "<tr>\n";
       if($r != $row) {
         for ($i=0; $i<$col; $i++) {
          $cell = $i+1;
	  print "<td>$cell</td>\n";	
     }	
     if($i == $col) {
          print "</tr>\n";
         }
       }
}
print "</table>\n";

Here is the whole shabang that you can taylor to your needs.
