foglio calcolo, misurazione minima

credo ti basti aggiunge alla condizione totale1 > 0
cioè:

codice:

<script type="text/javascript" language="JavaScript"> 
<!-- 
function dp(price)  
{ 
   string = "" + price; 
   number = string.length - string.indexOf('.'); 
   if (string.indexOf('.') == -1) 
      return string + '.00'; 
   if (number == 1) 
      return string + '00'; 
   if (number == 2) 
      return string + '0'; 
   if (number > 3) 
      return string.substring(0,string.length-number+3); 
return string; 
} 

function calculate() { 

var ops =""; 
var prezzomq = 275; 
var mismin = 200; 
var su_min = 2;  
var totale1 = dp(((document.calcform.altezza1.value)*(document.calcform.larghezza1.value)/10000))

var totale5 = dp(((document.calcform.altezza5.value)*(document.calcform.larghezza5.value)/10000)) 
  
document.calcform.totalfin1.value = totale1 
document.calcform.totalfin2.value = totale2

document.calcform.totalfin4.value = totale4

document.calcform.total1.value = dp(((document.calcform.totalfin1.value)*prezzomq)) 
document.calcform.total2.value = dp(((document.calcform.totalfin2.value)*prezzomq)) 
document.calcform.total3.value = dp(((document.calcform.totalfin3.value)*prezzomq)) 
document.calcform.total4.value = dp(((document.calcform.totalfin4.value)*prezzomq))
