First let me tell you i am trying to have a webpage (html/php) with a php created drop down menu call a java script function.
This function is supposed to grab a string from a php script and get a returned string.
This returned string is then injected into a specified div so that it creates a table based on the value set in the drop down box.
I am having issues getting a string returned from the php (which I suspect is because I am not properly calling the php function).
I am also having issues then with style. That is to say, the closest I have gotten is to not call the php file and just inject a string from the js file, but that string ends up not adhering to the style set forth in my css file.

}
the php file
<?php
var s = "";
$num = $_GET["num"];
for(i=0;i < num; i++)
{
*s += "<tr>
* * <td><input type='text' value='Phone Number (ddd-ddd-dddd)' id='num"+num+"' style='visibility:visible;' /></td>

s = ('<table class="victims">' + s);
s = s + ('</table>');
print(s);
?>
if my code is unclear I would be happy to go through and document it more to make it more easily understood.
Thank you in advance, Jake (Actingrude)
(Also if anyone uses coda on a mac with chrome as the preview, why does chrome download the php file instead of displaying it)
