Not sure this is a side-effect of a custom function in sqlite, but I was trying to use the queries to power a form. (here’s a rough demo http://www.thisisstaffordshire.co.uk/images/localpeople/ugc-images/275796/binaries/GPformMap4.html)

Slight problem is that if I use a query using certain terms the query returns data:

But others not including the electronic_prescription tag, don’t and return the following error:

{u’error’: u’sqliteexecute: sqlite3.Error: user-defined function raised exception’}

I think the problem is down to an error using a custom function to return a distance based on two lat/long-defined points.

What have I done wrong? More importantly, is it easy to fix?
