Median function not working

[Alex]

I can write a conditional count function for a given
dataset, but if I use the same input, it won't give me a
conditional median.

For example,
{=COUNT(IF((A$1:A$5="AZ")*(B$1:B$5=3),C$1:C$5))} 3
{=MEDIAN(IF((A$1:A$5="AZ")*(B$1:B$5=3),C$1:C$5))} #N/A

I have tried other functions like max, sum, and min. Only
count works with this dataset.

Do you have suggestions to what the problem might be?

Thanks
Alex
