Javascript help

[PELOU]

Field name: box1, box2, box3, box4, box5, box6, box7, box8, box9, box10, box11

Total1 = box1+box2+box3+box4

Total2 = box5+box6+box7+box8

Total3 = box9+box10+box11

Box3 = the amount from Total3

Total4 = Total1+Total2

Please I need the custom script for:

Total1, Total4, box3  

And to leave blank when equal 0

Thanks!!!!!

For Total1:

var x = Number(this.getField("box1").value)+Number(this.getField("box2").value)+Number(this.getField("box3").value)+Number(this.getField("box4").value);
if(x == 0)
event.value = "";
else event.value = x;

You can easily adapt code for other fields.

How do i write the condition for the same script above:  If  x  is less or equal to zero

Thanks!!!!

For less or equal use this:  <=
