Macro: mixed absolute and relative references for rows

Hi there,
I have a problem with the macro I'm trying to set up. I have the equation:

=MIN(IF($B$2:$B$5000=MAX(IF($B$2:$B$5000<(INT($B2)+1),$B$2:$B$5000,"")),$G$2:$G$5000,""))

that I want to convert into a macro. I need everything to be an absolute reference except for the $B2 of the INT() function. I want that to change based on the row that the data is being entered into (so row 2 is $B2, row 3 reads $B3, etc). However, here's my problem (and which is why I can't figure out a solution to adapt in other posts), the equation above is located in each cell in column H, but the data being entered is in column G. For example

A B C D E F G H
1
1.2
1.3 8/6/12
2

so using the equation (desired macro) above, H1, H2, and H3 would all populate with 8/6/12.

As a side note, even though I put "" in my equation, it still returns 0 (in this case, 1/0/1900) if the G cell is blank. Anyone know how to fix that?

Thanks for your help!

Oops! Sorry. My example didn't translate very well. The 1, 1.2, 1.3, and 2 are in B1, B2, B3, and B4, respectively, and the 8/6/12 is in cell G3


Thanks!
