Iterate over set of field ids using for loop

Hi Thomp,

I have a set of textfields with a button next to it, when i click on the button values will be shifted from one text field to other. Something like this:

myField__5.rawValue = myField__4.rawValue;
myField__4.rawValue = myField__3.rawValue;
myField__3.rawValue = myField__2.rawValue;
.
.

instead of doing like this i want to make it in a generic way by using a for loop, can you tell me how can i do that?

I tried like this:

for(var i =5 ; i>0 ; i--)
{
this.getField("myField__"+i).value = this.getField("myField__"+i-1).value;
}

but, its not working, is it the right way to do?

Thanks in Advance,
Pavan
