I feel there is something wrong with my if statements but i just can't figure it out.
It should check all fields when the save button is clicked and bring up a single message box stating the errors found. then the SQL statement is telling me that no null values cant be entered. Middle name, email address and either the H number or C number can be empty if one or the other has data.
