Search and if found then SUM

[The Animal]

Hi
I have one condition in below if "S" is found in B16 but would like to add PT so if "S" or "PT" is found then SUM if not leave cell blank
=IF(ISERROR(SEARCH("S",$B16)),"",IF(SUM($BO16,$BF16,$AW16,$AN16,$AE16,$V16,$M16)=0,0,SUM($BO16,$BF16,$AW16,$AN16,$AE16,$V16,$M16)))

Thanks for any help

How about

=IF(SUM(COUNTIF($B16,{"*S*","*PT*"})),SUM($BO16,$BF16,$AW16,$AN16,$AE16,$V16,$M16),"")
