Cannot add record via a form

Cannot add record via a form

when I tried to add a record via a form, the following error appeared:

1 . [t_441902000000010037] Exception occured while setting value in PreparedStatement for the Column [LastProjCl_441902000002951563] Check whether the datatype for this column is given as specified in the data-dictionary .[t_441902000000010037] Exception occured while setting value in PreparedStatement for the Column [LastProjCl_441902000002951563] Check whether the datatype for this column is given as specified in the data-dictionary

Anybody know how to resolve this?
