error trying to move data from 1 table to another.

Hi I am getting the following error
Syntax error converting the nvarchar value 'null' to a column of data type i
nt
while attempting to move data from 1 table to another with the script,
INSERT INTO [dbase1].dbo.DML$table1
([Data_Item_ID])
SELECT CAST([Data_Item_ID]as int)
from [DML1].dbo.dataitemlog
I have allow not NULL for both source and destination fields, so do not see
how I could be getting this error, also did not see any null values in the
source field. The source data type is
(nvarchar (4) not null)
and the destination field data type is (int, not null)
any suggestions? thanks.
