www.p o t s p a c [url removed, login to view] the distance selector doesn't work correctly. Please fix it and any erroneous or unnecessary code in the browse file. What I mean is if you enter a zip code such as 06778 and select a distance you still see everyone. At one time this did work however with so many programmers having modified the code, it no longer works.
I believe the best way to perform any search involving zip codes, is to first determine which zip codes are in range of that zip code. For instance if I select 5 miles of 06778 there are only a few zip codes within 5 miles, so only members within those zip codes are searched for, etc.
The next step would be to apply the additional search criteria on those results. I'm not a programmer so there may be a better way to do it.
