#1074 - Too big column length for column 'entry' (max = 255). Use BLOB instead

What'sa BLOB? &how do I fix it? In simple terms because my brain is a little... Eh at the moment.
Oh, and this is what I was trying to do....

varchar columns can only be up to 255 characters in length. You should use the type BLOB instead.
