Thanks for the reply!
I must admit i and confused by the answer to the global variables question.
Can i ask another question? What if i want to increment a global counter from within a
function. at the moment i am trying to declare the variable normally:
$counter=0;
then within the function:
function (){
global $counter;
$counter++;
}
but then when i go to echo $counter outside of the function its value hasnt changed?
Yet again any help would be appreciatted!
