Steve,

n my tests even though the documentation says you can use the field number, the setfldstate fails everytime I use the field number and succeeds when I use the field name. Try something like this;

laFlds = AFIELDS("CustUpd")
FOR lnCnt = 1 TO ALEN(laFlds)
    DO CASE
       CASE GetFldState(laFlds(lnCnt,1) = "4"
            IF NOT SetFldState(laFlds(lnCnt,1),2,"CustUpd")
                * Failed
            ENDIF
...

Also, change the tableupdate to;

IF NOT TableUpdate(...)
   * Deal with a failure

ENDIF

Also, why are those two variables declared PUBLIC? PUBLIC vars are a disaster waiting to happen.
