Try

=IF(J34="","",ROUNDDOWN(J34,2)

Also the AVERAGE in the other formula seems superfluous.

cell j34 - =IF(Input!K150,AVERAGE(J22+J33)/2,"")

This part works ok, putting the number in cell j34, or nothing.
However, I need the cell in j35 to rounddown 2 places the value in j34 if
it's 0, but also put nothing the j35 if there's nothing in j34.

I'm trying by using the =ROUNDDOWN(J34,2), but I'm getting an error.

Any help would be appreciated.

Thanks,

Steve
