Problem with Transaction Custom Field

Hi,

I have defined a “Transaction CF”.
I go to #TicketId =>Jumbo menu option, and set the Value for the
"Transaction CF". And it fails with this error when I click the Save button
(I use this menu option because I need to move the ticket to another queue.)

Does somebody know how to deal with it?
Thanks in advanced,
Gabriela

Here I paste the error:
