	Hi Dark! First you have to select the formfield with function FindFormFieldByTitle (for example) and with the returning (longint) id you can use color := QP.GetFormFieldBachgroundColorType(index); color (as an integer variable) should contain value 1 for gray. http://www.quickpdflibrary.com/help/quickpdf/GetFormFieldBackgroundColorType.php Cheers and welcome here, Ingo
