Not entirely sure what you're needing, but take a look at the GetRepetition function. By careful use of a loop and a counter in a variable, you should be able to extract the values.
Another approach would be to export your data to a new FM database, then import it back to a new table in the existing file, allowing FileMaker to separate the values in the repeating fields into individual records. That may work for you if your table structure will allow you to make the joins.
I have set up the revision history as a new table and would like to move my data from the 3 seperate repeating fields and place them into the new table, with each repeating field as its own record a
Simply import the data into the new table and select the option to split values in repeating fields into separate records.
Tried this and it worked like a champ. No issues what so ever. Thank you very much.
