Finding the Value with Highest Frequency in a Range

I have a range of numbers on column "A" where some of numbers have been repeated several times. My question is:" How can I find the value more than zero with highest frequency in a range?

I tried below formulas but it does not work truly (sometimes gives me true value and sometimes gives me wrong value). On the other hand, I need the value more than zero with highest frequency.

=INDEX(B:B, 10000*MOD(MAX(COUNTIF(B2:B16,B2:B16)+(ROW(B2:B16)/10000)),1), 1)

=INDEX(B2:B20;MODE(MATCH(B2:B20;B2:B20;0)))

Do you have any solution for my problem?

Thanks in advance for your cooperation.

Please see enclosed excel file.

=INDEX(B2:B20,MODE(IF(B2:B20<>0,MATCH(B2:B20,B2:B20,0))))

array formula
use ctrl + shift + enter
