Help for setting up an Equation

All right, i started to figure it out, but i’m stucked…The fist adjustment is OK… (i think ?? but how to connect it to the others?
(function(){
if( fieldname2 >= 33 && fieldname2 <=33.999) return fieldname1+30;
if( fieldname2 >= 32 && fieldname2 <=32.999) return fieldname1+20;
if( fieldname2 >= 31 && fieldname2 <=31.999) return fieldname1+10;
if( fieldname2 >= 30 && fieldname2 <=30.999) return fieldname1;
if( fieldname2 >= 29 && fieldname2 <=29.999) return fieldname1-10;
if( fieldname2 >= 28 && fieldname2 <=28.999) return fieldname1-20;
if( fieldname2 >= 27 && fieldname2 <=27.999) return fieldname1-30;
if( fieldname2 >= 26 && fieldname2 <=26.999) return fieldname1-40;
if( fieldname2 >= 25 && fieldname2 <=25.999) return fieldname1-50;
if( fieldname2 >= 24 && fieldname2 <=24.999) return fieldname1-60;
if( fieldname2 >= 23 && fieldname2 <=23.999) return fieldname1-70;
if( fieldname2 >= 22 && fieldname2 <=22.999) return fieldname1-80;
if( fieldname2 >= 21 && fieldname2 <=21.999) return fieldname1-90;
if( fieldname2 >= 20 && fieldname2 <=20.999) return fieldname1-100;
else return ‘N/A’;
})()

Hi,

The equation is simple, is only mathematics. In the problem description I’ll assume:

fieldname1: has an initial value that would be modified in function to the other conditions.
fieldname2: draw length.
fieldname3: arrow weight (in grains).
fieldname4: draw weight (in pounds)
fieldname5: bow string weight (in grains).

The equation would be:

(function(){
var result = 0,
f1 = fieldname1,
f2 = fieldname2,
f3 = fieldname3,
f4 = fieldname4,
f5 = fieldname5;

if(20<=f2 && f2 < 34 )
{
result = f1 + (FLOOR(f2)-30)*10;
result = result – MAX( 0, CEIL((f3-f4*5)/3))
result = result – CEIL(fieldname5/3)
}
else{
result = ‘N/A’;
}
return result;
})()
