I have created a link between tables by foreign key. I may have to leave this foreign key value blank ( as there might not be a valid entry for this field) . At the moment referential integrity is forcing me to not leave this foreign key value blank. Because I have a foreign key declared does this mean that I have to enter a value here. ??????????

Blank?  Try NULL (the reserved word, not a string!).  Make sure the column is "nullable".  It should work.

insert into table1 values('A',Null)
