Probably covered somewhere but... ajax to variable...???

OK - i'll admit it, only just started with javascript and Ajax today but
hey! got to start somewhere!!

Been playing with php for a while too so I'm not a complete nubie!

I've got a test ajax situation whereby it executes evey few seconds to
update the screen from something in the database...

the php script returns the number of rows in the releveant table (count(*))
and this is displays in the correspoding <div> secontion on the html page

Great!!

however...

What I really want to do is have the jaavascript part of my html page look
at the number returned by the php script and compare it to the value it last
returned. Only if the new value is bigger than the previous one, will the
<div> be updated by another php script.

in simple (vb!) terms:

b = 0
a = value returned from script.php
do
if (a>b ) then
run script2.php - update <div> with new data
b=a
endif
loop

can I do this with javascipt and ajax??

That do...loop is probably a bad example.... what my html page uses is:

var RecordCount = function()
{
new loadXmlHttp('ajax2.php', 'timeDiv');
setInterval(function(){new loadXmlHttp('ajax2.php', 'timeDiv');}, 1000);
}
