Trying to change a word type in BO to another word type

Below is the formula I am trying to create. It works just fine up to the last elseif statement. What I am trying to do is convert the "Preservation and Access" to JP2 and JPG. Not certain what I am doing wrong. Any suggestions would be greatly appreciated.

=If([Output Type]="Access")Then[Output Type]="JPG"ElseIf([Output Type]="Preservation")Then[Output Type]="JP2"ElseIf([Output Type]="Preservation and Access")Then[Output Type]="JP2"to"JPG"

Thanks,

Roger
