Enter this formula in B2 and copy down
=LOOKUP(2,1/C2:Z2,$C$1:$Z$1)
Change Z to the last column in your range

To hide #N/A till a date is entered use
=IF(ISNA(LOOKUP(2,1/C2:Z2,$C$1:$Z$1)),"",LOOKUP(2,1/C2:Z2,$C$1:$Z$1))

I have a work sheet with more then seven columns, each column has a cell with
a title in it. I want to know if it is possable to have a column with a
function or formula that will insert the column title if a date is entered in
that column.
I am using Excel 2003. See below for a picture of what I am looking for.
