I was wondering what is the best way of passing variables bewteen different windows/ pages? 

Is it possible to pass a starting value to the  using php like this <a href=”../rotaryevent/index.php?var=50“>OK</a>

and then get the variable like this:

    <progress class=”ui-circle-progress” id=”circleprogress” max=”100″ value=”<?php echo $var ?>”></progress>

Tried this but didn’t work. Guess there are better ways of doing it. any help would be very much appreciated.
