Debug Google Maps API on Charity Site (3 PARTS)

My charity website's signup form(s) for both client and volunteer users -- are becoming problematic since adding new fields and logic into them. I believe it's a Google Maps API issue as the address isn't being recommended nor populating accurately as it used to in prior versions. I urgently need an experienced freelancer with a proven background in fixing and tweaking Google Maps API issues to help resolve this. **** 3 PARTICULAR THINGS NEEDING FIX and TWEAK **** 1) Client Signup Form (see attached screenshot with URL for 'subscriber' user type) - This USED to work! 2) Volunteer Signup Form (see attached screenshot URL - from Step 3 of signup form for a Volunteer 'User') - This used to work! 3) I would like a mechanism in place for USA State Abbreviations: a. ONLY Accept the 2 Letter Abbreviation of any of the 50 states (when selecting Google Maps recommendation and populating into appropriate fields) b. IF user bypasses the google recommendation and population feature and they proceed to manually type in state, ONLY accept the 2 letter abbreviation + detect IF any of the 50 abbreviations are not typed as needed, they see an error message Key tasks would include: - Understanding the nature of these forms - Debugging the integration to ensure compatibility across all features - Fixing the address populating and eliminate any error messages / add mechanisms to stop it from happening on future tweaks You should have prior experience in dealing with Google Maps API integration especially with regard to web forms. Understanding of how to ensure data is saved accurately is a must for this project. Fast turnaround is appreciated as this issue is affecting our operation.
