AppleScript for address book text delimiter issue

In the following code, it should parse out the gps values from a map URL in my contacts, and save them one by one to a .csv file. Everything works, except there seem to be an issue with my text delimiters not pulling out the correct data. The URL in each contact is exactly the same as this example, only with different numbers:

maps:II=&q=30.34562,-92.41811

So I changed applescript's text delimiters to "q=", and figured the 2nd word would be "30.34562,-92.41811" which is what I need. but it's giving me other data like the two II's. Here's the complete code:

display dialog "This script will find GPS data in your contacts (in the URL field) and export it for Garmin's poiLoader to transfer to a GPS device. House numbers are included." buttons {"Continue"} with title "Export GPS data for GARMIN"set tid to AppleScript's text item delimitersset AppleScript's text item delimiters to " "set theTotal to 0tell application "Contacts" set _groups to name of every group set theirGroup to choose from list _groups with title "EXPORTING GPS DATA" with prompt "Select an Address Book Group" if theirGroup is false then say "No group selected.
