1. User can apply "Alert" action on "Error" event of Remove Marker Action.

2. Enter "__ERR_CODE__" in the Alert Title parameter.

3. Enter "__ERR__MSG__" in the Alert Message parameter.

Map Variables
S. No.	Variable Name	Description
1	_ERR_CODE_	ERROR CODE is the Name of the Error which is triggered during Map Action.
2	_ERR_MSG_	ERR_MSG is the Error Message of the Error which is triggered during Map Action.

If Google Maps API key is NULL or INVALID

1)In Preview (If key=NULL)

If User continued with out specifying the API key and previewed the app then a default alert for key will popup.

2) In Android and iOS (If Key=NULL)

In case of Android and iOS if the key is blank then "On alert" of Map actions will be triggered.

3) In MW, Android and iOS (If Key= Invalid)

In case Key is invalid or expired then all RTs will trigger "On Alert" event and the particular error message returned by the API will be stored in "__ERR_MSG__" Global variable

4) Preview/ MW cannot read API generated messages in case of API key NULL or expired. So "__ERR_MSG__" implementation is technical limitation.

5) The platforms behave differently as stated above when global error message (ERR_CODE) is used
