Hey stan, not sure if this helps you or not... but using an alternative
instead of VB code, which would be a much more complicated method then this.
But say you hide column B or put the data in Column C and hide Column C. In
column C put the formula

=If(Iserror(Match(A1,$B$1:$B$6,0)),"",A1)

Copy this formula and drag down to the end of your data... make sure you
change B6 to wherever the data ends and to make sure to keep the $ signs.

This formula will leave any value that does not match blank, and if the
value exists it will fill in the value. So you will get your desired
results... im just not sure if this is how you wanted to get them.

I have 15 minute interval data in column A and through vb code I need to
select the data in column B and have it moved to match the cooresponding row
in column A. In other words, if there isn't an interval of 6:15 in column B
then I want to leave that row blank. In the example below, the interval in
Column B row 2 should be moved to row 3 since it matches what's in column A.

Any help you can provide would be greatly appreciated! Many thanks!

Column A Column B Desired Results for Column B
1) 6:00 6:00 6:00
2) 6:15 6:30
3) 6:30 6:45 6:30
4) 6:45 7:15 6:45
5) 7:00
6) 7:15 7:15
