How do you use JSON decode with Google Maps API?

[Team DCM]

I'm having issues trying to use the JSON Text Decode function in AI2.

I'm trying to use Google Maps to get the distance between 2 lat/long points so I've got the response

I know that I have to use the look up in pairs function but I can't figure out how to get the elements such as 'text' under 'distance' - I keep getting the error 

"Lookup in pairs: the list (((elements(((distance ((text 0.8 mi) (value 1243))) (duration ((text 6 mins) (value 334))) (status OK)))))) is not a well-formed list of pairs"

 

I assume I'm doing something wrong in this bit above, any help would be greatly appreciated.

Thank you in advance.

rows is a list, see the [ bracket, which means, you have to use additionally the select list item block (to select for example the first item)
