If you want to save any data, and/or modify it later, you can use Variables.
GMetri experiences fully embrace "variables". Variables allow you to gamify your experiences and orchestrate a variety of interactions. If you want to add interactivity, you would almost always use variables (along with Rules).

Sources of Variables

Variables in GMetri come from three different sources:

Custom Variables

These are variables that you add manually to an experience. Go to Settings > Variables, select the type of value you want to store and click "Add Variable". You can then rename the variable from the table below.
Checking the "Tracking" option allows you to later check the values stored for that variable, for every user, in Analytics Dashboard
Adding Custom Variables

Global Variables

Global variables are available for use across all experiences in a workspace. The value of this variable is shared across experiences for any viewer.

Autogenerated Variables

These get added automatically. Check the list of autogenerated variables in Autogenerated Variables​.
