I want the Find string to search through a report, capture all the acronyms, and put them in a table at the beginning of the report. To do this the string is in a loop. Each time the code loops through the report and finds an instance of an uppercase group of three or more letters it place it in strAcronym (a string variable) so it can be added to the table.
As i said using just "<[A-Z]{3" & strAcronym & "}>" works fine except there is no upper limit on the length of the groups of letters it finds - and I just wondered why I can't simply add the 4 as that upper limit.
