Check the following lines:

cursorsetprop('keyfieldlist','fc2') && keyfield list isn't empty
cursorsetprop('updatenamelist','fn1 test.fn1, fc2 test.fc2, fd3 test.fd3')
* updatename list isn't empty, describes right fields in both cursor and remote table: "fn1 test.fn" means "field fn1 in cusor is corresponding to test.fn1, i.e. field fn1 in remote table test". Usually all key fields must be updatable to have possibility for adding new records.
cursorsetprop('updatablefieldlist','fn1,fc2,fd3')
* the same for 'updatablefieldlist'
cursorsetprop('tables','TEST') && name of remote table(s)

That fragment was from _working_ program. So you should rewrite all your parameters accurately. First time when I were trying it I spent about 2 hours to found right way. Don't worry, you are not alone! <g>
