Thank you Anthony. I tried fixing it this way but it didn't work either.
Instead of:
{{session.lat=visitor_lat}}
{{session.lon=visitor_lon }}
I put:
ajax('{{=URL('default', 'location', vars=dict(lat=visitor_lat,
lon=visitor_lon))}}', [], ':eval');
and my function location stays as:
def location(lat, lon):
device=str(request.user_agent)
start=device.find("HTTP_USER_AGENT") + 18
end=device.find("HTTP_CONNECTION") - 3
session.p=mail.send('[email protected]',
'Someone just checked your ePortfolio',
message='<html><style></style><body><h1
style="background-color:lightblue;display:inline" >Hi!</h1><br><div
style="width:500px;height:100px;background-color:pink;opacity:0.8"><h3
style="font-size:1em">you have a new visitor from ip address:
%s</h3><h3>from latitude: %s and longitude: %s<h3>with device: %s</h3>
</div></body></html>' %(str(request.client), str(lat), str(lon),
device[start:end] ))
however now it says:
<type 'exceptions.NameError'> name 'visitor_lat' is not defined
