Options are grayed out
I have an app I have been very happy with, filtering text reports into usable data. I am using text functions to parse the data. What I have noticed as a problem is that some of text fields have options grayed out when I right-click on the field. UNSORT, REPLACE (ctrl-=), and a couple others. I was trying to use replace. I don't get any error messages. Just the results are not what I expected. I have looked at all I can think of... suggestions?
