On the right hand side of a case there is an area where you can 'Add Score.' This is highlighted in the image below.
The below image shows the Available Scores and these are set up under Scores & Goals in case settings. All Scores have to be predefined so if they are not set up in case settings then they will not appear in this list.
For this example I have clicked on the 'PSFS' score. It brings up the image below.
You enter the value in the 'Score' section and then click 'Add.'
This then appears on the graph which you can see in the image below.
If you want to work with scores on a more detailed screen, simply click 'Advanced' on the score entry tab.
This will then bring up the below window, allowing you to enter scores and view the graph.
As the case progresses, if you choose to use the same score, you will see that the scores are recorded and the graph will represent the progress.
