To be able to add the test results in a range format you will need to go to ADMINISTRATION -> INVENTORY -> TESTING TYPES. On the testing types window you will need to add the ranges used ex: THC(min) & THC(max). This will add the type to your test results page so that you can input the results accordingly. As for the adding testing results to your label, a variable will be added in the test results option where you can then add the results in the Range format that is required.
