    Try giving a different name to the clear() function, like say clearValues() or clearFields():

    function clearFields(){ // name changed

    document.getElementById("c1").value='';
    document.getElementById("c2").value='';
    document.getElementById("c3").value='';
    document.getElementById("c4").vaue='';
    document.getElementById("c5").value='';
    document.getElementById("c6").value='';
}

    This may be due to the fact that clear() is used by the browser. Though I couldn’t find any reference for clear in javascript keywords accept this.

    Also you may find this answer helpful as it is related to the use of clear and also this related to reserved words in javascript.
