You should use original.value in the second line instead of just original
Yea I tried that and it didn't work.
Well, you have to keep it that way, and in line 3 change it from result.value to result. Only Field objects have a value property, and result is not a field property.
Thanks, that seems to have done to trick.
Here's the code:
var original= this.getField("Text3")
var result = Math.round(original.value*100)/100
getField("Text5").value = result
