document issue

Hi…I am using COM class to communicate with MS word and print my report. but when i am using Item() an error is thrown >> “Method ‘Item’ in COM object of class ‘Tables’ returned error code 0x800A1735() which means: The requested member of collection does not exist.” Please give me some clue to get through this error.

It means that there is no item with the given index. See also Requested Member of the Collection Does Not Exist.
