Sapscript: copy from client problem

Hello,

I developed sapscript in client 571. I'd like to copy it to client 572. So I go in se71 (client 572) to Utilities-> Copy from client and put 571 to field source client. I put the same name to Form name and Target form. I recieved message: "Changes to Repository or cross-client Customizing are not permitted". If I put 000 to field source client, the message is shown: "Form ZUA_LPR_LOSS_REC language * is not available in client 000". Can anybody please tell me what's wrong?

Best regards,

Josef Motl
