Javascript on a pdf form to change the colour of a field depending on the value in another field

[hollyj32411969]

I have used the following code to change the colour of a text field in a PDF form depending on the value entered into that field.

var v = +event.value; {
if (v>=1 && v<=5)   
event.target.fillColor = ["RGB",0.537,0.776,0];  
}  

Can anyone suggest how I can modify this code to change the colour of another field?

I want to change the colour of field "Text453" depending on the number entered into field "RISK"

(I have posted this question on another forum.)

OK, that's not quite what you described. You can change the color of the entire field based on the selection made in it, but not of an individual item. And no, it's not likely to work on almost any mobile device.
