Striptonum( function doesn't want to work

In the code snippet below, the striptonum( function has no effect. The initial data in the field is alpha-numeric and remains unchanged. The file has about a million records and 20 fields. If I preface the striptonum( function with a message statement, it does work.

field 1
    fieldName = info("fieldname") 
    if fieldName contains "alpha"
        formulafill striptonum(«»)


I’ve rebooted, reinstalled and restarted, all to no avail. very strange.

My fault - I had failed to save the changes :frowning:
