Bill is right on the money, make sure it is from the spot color swatch. I have issues with this in X4. Sometimes it reverts back to cmyk values and stops working. It also stops when I try to add it to my cmyk pallet so I made a pallet just for it. I don't seem to have any problems with it in X3. Opened ticket on it with Corel and Roland when X4 first came out. The issue is resolved in a big way in x5
