Leave blank if error

I would like to know how to make this formula not show #DIV/0! error if there is nothing to average.

=AVERAGE(H86:K86)

Thanks for you expert knowledge and help.

If you use XL 2007 (what would be nice to write in your profile) you can use IFERROR formula

=IFERROR(AVERAGE(H86:K86), "")

If you use previous version you can count values first:

=IF(COUNT(H86:K86)>0, AVERAGE(H86:K86), "")

Write in the profle please... Nobody will see this post next time you ask a question
