Palm Treo 700w / 700wx

I've managed to add my personal ring tones and they are working great for phone calls. I went into the Sounds and Notifications and under Notifications I went to "Messaging: New text message" and Messaging: New e-mail message" checked the box for play sound and put my custom ring tone in. Under the Sounds tab I have the "Programs" box checked and the sub-box "Notifications (alarms, reminders) checked as well. But when I get a text message I get no sound, any help would be appreciated. Thank you.
