I'm no expert, but from what I understand you should be getting a very high number, indicating increased resistance due to the cut bridge. Actually, some multimeters show "infinite" resistance. If the bridge was not cut, the resistance would be very low since the bridge is still intact and able to conduct a current. It sounds like your problem is you haven't cut the bridge yet since your multimeter is showing no resistance. Make sure the number you are reading is in "Ohms" of resistance.
