Steady AnalogSerialRead signal

Hello!

Here is my problem: My distance sensor's serial read is steady at 30. I am just running the basic AnalogSerialRead code to test it using an Arduino Duemilanove. There is no change as I change the distance of things in front of the sensor. I do not think its an external wire cross issue because. Is my distance sensor that is broken? I tried the same AnalogSerialRead code with the same distance sensor on my Lilypad as well, same issue, only this time the serial read is stuck at 24-5. I think there may be a simple fix to this, its been a long time since I have used arduino. Thanks

And a long time since you asked a question. What sensor do you have? How is it wired up? What code are you running?
