Please help with SUM formula dependent on results of other cells

[mrl]

In cell L12, I need to add across D12+F12+H12+J12; but only if there are
percentages showing in D12,F12,H12,J12.

I have formulas in those cells returning results. I do not want anthing to
show in cells L1 through L11 (null) if L12 has a total;(same calculations for
other rows). I ran into Circular referencing when I first tried this. I
changed the iteration, but then I was getting a FALSE return with the
different formulas I tried to put in, or the SUM formula just didn't work.
Please Help! I don't want 0% showing in the cell for the rows that do not
get added across, as it is now. Here's the formula I came up with:
=IF(AND(J12="",L12<>""),0,IF(AND(J12<=I12,L12<>""),SUM(D12+F12+H12+J12)))

The generosity of your knowledge is greatly appreciated.

This will sum every other cell in a range going across


=SUMPRODUCT(--(MOD(COLUMN(D12:J12),2)=0),D12:J12)

Thank you for trying, but this is not what I need. I need the cells in this
same column to be blank if one of the rows (in range) has formula results.
There are 12 rows across 6 columns - only one row (within all 6 columns) can
have results. The formula I am looking for will SUM the row that is showing
percentages in each of the columns (per the formulas already residing in
those cells)

Can anyone please help?
