change InputTitle and InputMessage in columns from row 2 thru 1000

[John L]

Hello,

I have 60 columns and 1000 rows with column title in row 1.

How would I adapt the following code to specify a different InputMessage
(IM) and InputTitle (IT) for each column row2 to 1000? Each cell in the
column (except row 1) has the same IT and IM. Or, does it need totally
separate code?

Specifically, is there a way to do it without writing 60 blocks of code?
Perhaps by specifying a cell range for IT and IM on another sheet? There are
columns not specified in the ranges below because they are not yes/no.

Thanks in advance,
John
