Can I use OR for the filter
You cannot use OR for the filters currently. But there is several ways to resolve this.
So we can do the opposite and filter out all statuses that we don't want on the leaderboard.
The above screenshot of the leaderboard filter reads as:
Status is not new_call AND Status is not sold_call
This would work as we are now excluding all other options so the leaderboard will only give points if the status is not one of the ones in the filter.
If you are using Salesforce for the leaderboard goal you could Create a custom flag in SF that tracks if the status is opp_call or lead_call and use that by Customizing Salesforce Fields.
