Copy a validation java script into multiple fields

Hi,

I have a PDF form which acts as an inspection report for a manufacturing process at my work. I am trying to digitise the report so they can use a tablet instead of hand writing and then scanning the documents into our system.

I have a simple validation script which turns the entered text into red for certain values:

function if (event.value=="WORN") event.target.textColor = color.red;

else event.target.textColor = color.black;

However i am not having much luck copying this script to all the text fields on the document (over 200 fields).

I have tried the solution outlined in this thread: faster way to copy a validation java script into multiple fields, i have set a Document JavaScript called validateField, i have then put the following script into it:

function validateField()

{

function if (event.value=="WORN") event.target.textColor = color.red;

else event.target.textColor = color.black;

}

But when i run the  JavaScript console it just adds validateField() into the Text Fields custom validation script section and not the script above. This is what i am running the the JavaScript Console:

for (i=1; i<=200; i++)

{

    this.getField("Text Field Condition.1."+i).setAction("Validate",'validateField()');

}

Am i missing something?
