Trying to remove #DIV/0! error in calculated field

[nmss18]

Hello,
I added a calculated field (named average of handled calls) where I divide the number of calls handled up by a client service rep by the number of calls presented. The problem is there are some clients that recieved no calls at all and the calculated field returns a #DIV/0! error ( see table below). I tried various formulas in the calculated field to try and remove this without any success.
This is the formula I am using:
=IF(ISNUMBER('Calls Presented'),'Calls Handled'/'Calls Presented',"")

When I try using this formula:
=IF(ISERROR('Calls Handled' /'Calls Presented' ),"",'Calls Handled' /'Calls Presented' )

I get a #VALUE! error.

I have seen some previous dsicussions in this forum noting others with this issue but the solutions recorded there did not work for me.
Any advice here would be appreciated.
Thanks,
nmss

There may be an easier option.

If you go into your Pivot options, first tab, there's a "For error values show" option you can check to display blanks on errors.
