js: 

var wejscie = document.getelementbyid('eq').value;    if ( wejscie <= 100000) {     var stawka13 = 59;     var stawka46 = stawka13*0.75;     var stawka710 = stawka46*0.55;   }   else {     var stawka13 = wejscie/100000*59;     if (stawka13 > 210) {       stawka13 = 210;     }     var stawka46 = stawka13*0.75;     var stawka710 = stawka46*0.55;   }    stawka13 = math.round(stawka13).tofixed(2);   stawka46 = math.round(stawka46).tofixed(2);   stawka710 = math.round(stawka710).tofixed(2); document.getelementbyid('sum13').innerhtml = "";   document.getelementbyid('sum46').innerhtml = "";   document.getelementbyid('sum710').innerhtml = "";   document.getelementbyid('sum13').innerhtml = " "+sum13+" zł";   document.getelementbyid('sum46').innerhtml = " "+sum46+" zł";   document.getelementbyid('sum710').innerhtml = " "+sum710+" zł";
