Do you know how I would be able to fit your advice into the following formula

=INT(AVERAGE(P2,S2,V2))+CHOOSE((MOD(AVERAGE(P2,S2, V2),1)<0.3)+(MOD(AVERAGE(P2,S2,V2),1)<0.7)+1,0.9,0 .5,0.1)

as when I try I keep getting errors
Thanks for your help

=AVERAGE(IF(NOT(ISNA(A1:A3)),A1:A3))

ctrl+shift+enter, not just enter

I am trying to take the average of some data but some of the cells contain
errors (as there is data missing for the function to calculate). In my
database there will always be some missing data so these errors will be
present. Is there any way of taking an average of data that contains errors?
eg. average(a1,a2,a3) equals 4 whe
a1=5
a2=#N/A
a3=3
Many thanks for your help
