Create a Condition for it within your charting section. Go to Conditions icon, select, and then when the options pop up, create a condition. EXAMPLE: CHIP Porc Only so many letters will appear on chart, so be selective, also, you will want the option of Tooth required to be selected. Once a condition is created it can never be re-used or deleted, therefore, once again be careful. They can be inactivated. I hope this helped
