Hi,
I have the code below which exports my contacts - which is in an SQL table - to an Excel file. The code works fantastically. The only problem I have is that sometimes when people submit the form to add their contact information to my database, they tend to leave some fields blank.
The columns on the table go "First name" "Last name" "Email" "Phone" etc.
If someone left the first column blank, then when the Excel file is printed, it will display the "last name" field in the "first name" field and the "email" field in the "last name" field and the "phone" field, in the "email" field and so on. Everything moves to the left to replace the missing "first name" field.
I would really like to have this fixed, but I am unsure how. I am assuming a "for" statement should be used but I am unsure how.
Thank you!
