Trigger with Custom States
I've written about this text manipulation requirement before in previous blogs, but most recently I've had to replicate the Trigger for multiple clients.
To help with this, I've revisited the code and have started using Custom Settings to store some of the detail and make the Trigger more easily customisable.
Utilising Custom Settings had great promise, it was a good learning curve for me as well to work out how to create the Custom Settings within the Test Class to ensure coverage.
The Custom Settings
Here is the custom setting file I created for this project.

The Trigger
trigger Tagged_Custom_State on NVMStatsSF__NVM_Agent_Summary__c (before update, before insert) {
/*
In this trigger we need to look for a list of Custom States in a string and add up the totals for each.
Example Key Event field
53344Custom State 304:04|
53344Custom State 305:05|
53344Custom State 320:20|
53344Custom State 321:21|
53344Custom State 322:22|
53344Custom State 323:23|
53344Custom State 324:24|
