    add up results of other functions on the fly

    I have ten functions (I know this is a drawn out way of coding) and the last function doesn't work.

    Its supposed to total up the result of the first 9 functions, but it doesn't change my input at all.

    can I resolve this?

    Code:
     <script type="text/javascript">
    function updatesuma(){ document.form.suma.value =(document.form.sum1a.value-0)- (document.form.sum2a.value -0); } 
    function updatesumb(){ document.form.sumb.value =(document.form.sum1b.value-0)- (document.form.sum2b.value -0); } 
    function updatesumc(){ document.form.sumc.value =(document.form.sum1c.value-0)- (document.form.sum2c.value -0); } 
    function updatesumd(){ document.form.sumd.value =(document.form.sum1d.value-0)- (document.form.sum2d.value -0); }
    function updatesume(){ document.form.sume.value =(document.form.sum1e.value-0)- (document.form.sum2e.value -0); } 
    function updatesumf(){ document.form.sumf.value =(document.form.sum1f.value-0)- (document.form.sum2f.value -0); }
    function updatesumg(){ document.form.sumg.value =(document.form.sum1g.value-0)- (document.form.sum2g.value -0); } 
    function updatesumh(){ document.form.sumh.value =(document.form.sum1h.value-0)- (document.form.sum2h.value -0); }
    function updatesumi(){ document.form.sumi.value =(document.form.sum1i.value-0)- (document.form.sum2i.value -0); }  
    
    function updatesumtotal(){ 
    document.form.sumtotal.value =
    (document.form.suma.value -0)+ 
    (document.form.sumb.value -0)+
    (document.form.sumc.value -0)+ 
    (document.form.sumd.value -0)+
    (document.form.sume.value -0)+ 
    (document.form.sumf.value -0)+
    (document.form.sumg.value -0)+ 
    (document.form.sumh.value -0)+
    (document.form.sumi.value -0) 
    ; } 
    </script>
    HTML Code:

    If I recall correctly, a javascript cannot read the value of a "readonly" field.

    To pass the value, use the "input hidden' field.

    That's not correct. Read-only fields just can't be selected by the user - it does not limit any script's access in any way.
