how come this is not working

[rcirone]

=iferror(=a2),,iferror(=a2)

That is not a valid formula construct.

See here for the construct of IFERROR:

Perhaps this is what you are after:

=IFERROR(A2,"")

If not, please explain exactly what you want to happen, in plain English.

 

[Dan5977]

=iferror(a2,"")

 

[rcirone]

if I use both I still get the 0 to show up how can I not get the 0 to show up

Is this what you are after?

=IF(A2="","",IFERROR(A2,""))

If not, please explain gives us a detailed explanation of what you have and what you want to happen.
