Narrative:

Arriving into phx on the geela 2 arrival; we were cleared to descend via the arrival and then told to delete speed restrictions. You can't just delete the speed only on the CDU; so I deleted the line and then retyped the altitude. I believe I might have put in 11;000' instead of 10;000'. Five miles later; as we were reaching 10;000 feet; the controller asked our altitude. She mentioned we were supposed to be there a few miles ago. I think if ATC is going to change any of the descend via [clearance] and not allow you to just fly it as published; they should revert to altitude and airspeed directives. I also believe I won't be retyping altitudes on arrivals just using the airspeed override button.

Original NASA ASRS Text

Title: A B737 Captain arriving PHX on the GEELA 2 was instructed to delete the speed restrictions. An altitude deviation; that was noted by the Controller; was the result of an FMC programing error.
