Allowed Values list of a CCK field.

I have a CCK field that is an integer value. I have defined the minimum to be 137812 and a maximum of 160242. (Not sure I would even need to do this if I could get the allowed values list to work)

What I want to do is between the minimum and the maximum carve out other "allowed values".

Using the allowed values listing, I would need to add nearly 3000 values if I were to list each individually.

Is there any way to use <, >, <=, etc. to allow, for example, 137812<=137835, 138551<= 139223, etc and not have to code all 3000 unique cases?

I've not had any luck using 0|137812<137836, 0|137812-137835, or other combinations using the key|label. What am I missing?

Any ideas?

Sorry, I do not know PHP.
