Thread: Multiple IFs in a statement is confusing.

I got an if statement that says this

=IFERROR(IF(Q3="","",IF(Q3<0,Q3*(('MLB OVERALL'!$O$2*'MLB OVERALL'!$D$3)+$A$3+I3+O3)/-100,
(('MLB OVERALL'!$O$2*'MLB OVERALL'!$D$3)+'Week 1a'!$A$3+I3+O3)/$Q3*100)), "")

However the part I am concerned about is this

+$A$3+I3+O3

What I need is this to be added someway I will write it and see what you guys think

if J3="P" then do not add I3 and if P3="P" then do not add O3.

so in this example in row 10

if
J10=L
P10=P

then it would be


+$A$3+I3

Any help would be greatly appreciated
