Firefox versus IE

I have a web page that works perfectly with Firefox but fails with IE. Please tell me what needs fixing. I have extracted the bits I think are relavent as follows:- <form name = 'SelectEvent' ID='SelectEvent' method='get' action='AdjustmentReport.php'> and <BUTTON TYPE='submit'>Submit</BUTTON> if (isset($HTTP_REFERER))

    {
    echo "<a href='$HTTP_REFERER'><BUTTON TYPE='submit'>Back</BUTTON></a>";
    } else {
    echo "<a href='javascript:history.back()'><BUTTON TYPE='submit'>Back</BUTTON></a>";
    }

neither the submit nor the back buttons work in IE but both work fine in Firefox. Javascript is enabled in both browsers. -- Regards, Alf Stockton www.stockton.co.za Clothes make the man.
