sumif blank values

[Sasquatch2014]

I have the following formula. If the there is nothing to sum the value in the cell is 'o', I would like to change that so the cell is blank instead.

=SUMIFS('csr data'!H:H,'csr data'!O:O,Production!B5,'csr data'!R:R,Production!$D$4,'csr data'!P:P,Production!$D$3,'csr data'!H:H,">0",'csr data'!A:A,">"&Production!$B$1,'csr data'!A:A,"<="&Production!$B$2)

without seeing anything else or testing your formula this should work...
=if(SUMIFS('csr data'!H:H,'csr data'!O:O,Production!B5,'csr data'!R:R,Production!$D$4,'csr data'!P:P,Production!$D$3,'csr data'!H:H,">0",'csr data'!A:A,">"&Production!$B$1,'csr data'!A:A,"<="&Production!$B$2)=0,"",SUMIFS('csr data'!H:H,'csr data'!O:O,Production!B5,'csr data'!R:R,Production!$D$4,'csr data'!P:P,Production!$D$3,'csr data'!H:H,">0",'csr data'!A:A,">"&Production!$B$1,'csr data'!A:A,"<="&Production!$B$2))
