validate code for multiples

[tmargherio]

what is the javascript validation code for multiples of 6.  I have created a fillable order form in acrobat and certain items can only be ordered in multiples of 6. So i want the quantity field to only accept numbers that are divisible by 6.  thanks

Use this code as the field's custom validation script:

if (Number(event.value)%6!=0) {
    app.alert("You must enter a value that's a multiple of 6.");
    event.rc = false; 
}

THANK YOU!

You might want to add checks for a minimum value (e.g., 6, since -18 % 6 = 0) and a maximum as well, and blank.

Good point, although the code above will accept blank values.

If the list of possible allowed items is quite limited I would recommend using a drop-down, instead of a text field.
