    Refresh Page - Unless Condition

    Hey Guys,

    Hoping that you can help me, as I have been scratching my head and
    getting nothing but dandruff...

    SITUATION
    ---------
    I have a webpage which users will be viewing, which has forms which can
    be hidden or displayed at the user's choice. The problem is that they
    want the page to refresh every X seconds, but if it refreshes when a
    form is displayed, then the form loses the entered data and disappears
    as the screen is redrawn, meaning the user has to write it all up
    again.

    MISSION
    -------
    I want to create a JavaScript refresh function, which will only refresh
    the page if a certain condition is met. The condition will be a
    variable which will count the number of forms currently being
    displayed. If the variable ('openForms') is 0, then the refresh should
    be executed.

    ATTEMPTS THUSFAR
    ----------------
    function refreshCounter( ) {
    Id = setTimeout( refreshWindow() , 100000 );
    }
    function refreshWindow() {
    if ( openForms==0 ) {
    // No Windows Open - Reloading
    window.location .reload(true);
    } else {
    // Windows Open - NO Reload
    }
    }

    RESULT THUSFAR
    --------------
    The page was constantly trying to reload the second it opened - causing
    a loop which only stopped when I commented out the second line of
    "refreshCounter ()".

    Any suggestions, or assistance would be appreciated.
    Am I doing this the easiest possible way? Or is there a better option?

    Thanks
    Luke

      <SNIP>
      Id = setTimeout( refreshWindow() , 100000 );
      should be
      window.setTimeo ut("refreshWind ow()",100000);

          Hi "Jedi Fans",

          Thanks for your lightning quick response!!!!

          Such a simple error and a messy result...
          I have made the modification as suggested and, for the first run
          through, it worked - I had a form open (so the condition would prevent
          the refresh from happening) for the first cycle, and then I hid it (so
          the condition would let the refresh happen) the second time, but it
          looked like the loop ceased after the first run.

          Any further suggestions on how I can achieve this?

          Thanks
          Luke

                      yvw Luke, also unless your email address doesnt mind being spammed...
                      best to munge it like this:
                      lucanos[at]gmailNOSPAM[dot]com or summin invalid so the spammers dont get it
