Hi,

This one is puzzling me :/ 
if (
            ($long > 180 || $long < -180) 
            || 
            ($lat > 90 || $lat < -90) 
            || 
            $long !~ /^([\d\-\.]+)$/ 
            ||
            $lat !~ /^([\d\-\.]+)$/
            ) {
        
..show error here
        
        }

I'm trying to make sure that the long/lat values pased in only consists of stuff like -4.332423424 , 0, 4.434 , etc

...for some reason, the above code never matchs though. These 2 lines work fine: 
            ($long > 180 || $long < -180) 
            || 
            ($lat > 90 || $lat < -90)

....but the regex stuff never seems to match.

Am I missing something silly? Been working on this for the last 20 mins, and still can't work it out :(

TIA!

Andy
