Hi,
Is it possible to create two custom field options just like price: year range and mileage range?
I have been trying to create one since 3 years now and still nothing. A car classified website does not make any sense without them, so please i would appreciate if you would show me what i need to create or modify? Maybe copying price script and paste?

Ps i have already bought car attributes plugin, but its somehow not doing the work i need and too complicated. Custom fields are much cleaner and better.

 
Thank you

Its not simple feature so that could be reason.

You have already created that in Attributes Pro plugin, even more complex. But still its your decision at the end, you are the expert of the field.
