Looks like GetMap is a custom function on the preset database.
I've not used it myself, but this thread may offer some help for you :
You have exceeded your daily free usage of Google maps. It should work again tomorrow. The allotment (number of times you access the Google Map) is a rather large number so it may be a problem with the way you are using the Google API. If you exceed this on a regular basis, you should contact Google for a high usage license.
Would it be because I copied like 7000 records into the database and all the address linked up to show the map? so would that be why? As I wouldn't need to do that again?
Thanks a lot
That sounds like a plausible cause. Try your solution again later to check that the allocation has been reset by Google.
You might want to consider not displaying the map unless a user clicks a button or opens a tab/sliding panel/pop-over with map on it. Are you using Form view? Try to avoid Table and List views.
