I am using the following formula to display in cell xx £200 ( I have
altered this slightly as it used to display two different values, 150/200 to
200/200)

=CHOOSE(MATCH(D7,{0;5;7;11},1),"",200,200,"")

The value (£s) is triggered by the month of the year 06/07/08/09 etc, I had
a person fill in the form using Sept rather than 09 and the displayed N/A

Is there a way around this? Or does it just complicate things too much.

thanks
