Hi there,
The above sample file is a simple pdf file which has only one combo box (drop down menu). What I intend to do, default color of this drop down menu will be white. But when an user will select "One", it will become green in color, if select "Two" it will be yellow and if "Three" it will be red. I have put the following validating script in the form:

var f =;    
var fv = event.value;

if (fv == "One") {
    f.fillColor =;
else if (fv == "Two") {
    f.fillColor = color.yellow;
else if (fv == "Three") {
    f.fillColor =;
else {
    f.fillColor = color.white;
It is created in Nitro Pro 8 version. However, although it is working well in Adobe Acrobat but it's color is not changing in Nitro itself. I have tested it both by turn off and on of Highlight Form Field option. It is also not happening if opened by google chrome buil-in pdf viewer.

Would someone download and check why this is occurring in Nitro Pro 8?

Any help will be appreciated.
