Ginsterman,
Just for reference, since you are only looking for a "yes" or "no" for the "plan in place" custom field, a Flag field seems more appropriate (i.e. no need to create a value list). So, while waiting for you to respond to my latest post, I assumed the Flag1 field is used for the "plan in place" and I used the Text1 field for the graphicical indicator field. Here is the formula, using the fields I chose, to do what you want. However, if you really have your heart set on using the Text1 field for your "plan in place" field, then you'll need to tweak the formula to look for "yes" or "no" instead of true and false and of course put the formula in whichever other field you are using for your graphical indicator.
Give it a test, let me know if I missing anything.
