I have a SP that is supposed to update the current table. I get "Cannot update the cursor DEALERS, since it is read-only." The table is not read only. Does anyone know why I would get this read only error message from running the stored procedures?

Here are the SPs:
FUNCTION spDealersInsertTrigger()
? ISREADONLY()
REPLACE ChangeDate WITH DATE(), Change WITH "NEW"
RETURN
ENDFUNC

FUNCTION spDealersUpdateTrigger()
? ISREADONLY()
REPLACE ChangeDate WITH DATE()
RETURN
ENDFUNC

Here is the GENDBC code:
DisplayStatus([Creating database...])
CLOSE DATA ALL
CREATE DATABASE 'MYDBC.DBC'
DisplayStatus([Creating table DEALERS...])
MakeTable_DEALERS()
DisplayStatus([Finished.])

FUNCTION MakeTable_DEALERS
***** Table setup for DEALERS *****
CREATE TABLE 'DEALERS.DBF' NAME 'DEALERS' ( ;
COMPANY C(45) NOT NULL, ;

ADDR2 C(45) NOT NULL, ;

ST C(2) NOT NULL, ;

***** Change properties for DEALERS *****
CREATE TRIGGER ON 'DEALERS' FOR INSERT AS spdealersinserttrigger()
CREATE TRIGGER ON 'DEALERS' FOR UPDATE AS spdealersupdatetrigger()
ENDFUNC

FUNCTION DisplayStatus(lcMessage)
WAIT WINDOW NOWAIT lcMessage
ENDFUNC
