Nested IF and IFERROR

I am trying to write a formula that will check to see if there is an error in a specific cell and them return a value based on that. This is what I have so far.

=IF(IFERROR(C3, TRUE),IF(IFERROR(E3,TRUE),A3,""),"")

But all I am getting is A3 on the first 20 items on my list. Only about 6 of those should display data from A3.

Need some help figuring out what went wrong.

If I understand right..
If C3 is NOT an error, then return the value of C3
If C3 IS An error, then move to A3
If A3 is NOT an error, then return the value of A3
If A3 IS an error, then return ""

Try

=IFERROR(C3,IFERROR(A3,""))

close.

IF C3 is an error, check if E3 is an error. If E3 is also an error then enter A3 into the cell.
IF C3 is an error, check if E3 is an error. IF E3 is not an error then enter blank into the cell.
IF C3 is not an error, enter blank into the cell.

Thats the way it should work.

So only if BOTH C3 and E3 are errors, then return A3
otherwise return ""

Is it REALLY only these 2 cells?
Or are you planning expanding to G3 I3 K3 etc. ?

Nope. Just those two. It will go down several rows but no more columns.

And yes only if both are errors.

And what type of data is in the cells when they are NOT errors? Number or Text ?

Try

=IF(ISERROR(C3),IF(ISERROR(E3),A3,""),"")

A eight digit number.
