How can I make an object print a yellow color on print out?

Hi All,

I have a form that I am currently working on. The check boxes are grey color on screen, but should print yellow color on printout.

I wrote the following script on the Preprint event.

form1.Page2.Marginalchbx.fillColor = "255, 255, 0";

This is not working, and I do not know why it is not. Is there someone out there that can helpout. I greatly appreciate it.

Thanks

Tammy
