Writing a script in a PDF form so colour of text changes based on a value.

[GlenPenny]

I have a simple script but not sure what is wrong. Basically if the number input to the form is less than, for example, 5. Then turn the font colour red. It works but.. not if you input 0.

var A = Number(this.getField("Quantity").valueAsString);

if(A){
 if(A<5)
 event.target.textColor = color.red;
 else
 event.target.textColor = color.black;}

The first if statement blocks the 0 input, because a value of 0 converts to False.

Remove it. Here's an update.

var A = Number(this.getField("Quantity").valueAsString);

if(A<5)
   event.target.textColor = color.red;
else
   event.target.textColor = color.black;

This has solved the issue. Much appreciated!
