Conversion failed when converting the varchar value ' ' to data type int.

This won't affect anything.

Go to where you are adding the value for 'CCAF', make sure that you are indexing the row with that column name and not just passing that column name (sneaking suspicion). Which value index of the row is CCAF supposed to be? The error is quite clear, you are passing in the value 'CCAF' when it is supposed to be a number.

CCAF goes under the column name ALIAS its a varchar in my database, and its not supposed to be a number.
