If Emir's suggestion does not work for you ... likely the value is NULL and that is why your formula is not working. There is technically nothing there to change the background color of .
Likely you are trying to highlight missing data int he report. If you do not want tio change the way your report handles NULLS
You can do this via a formula field and formatting
Create a formula field to convert your NULLS to one space or any text you want (like 'Missing'). You will also have to convert the T0_Field1 to text if is not.
if isnull({vw_Asset.T0_Field1}) then " " else {vw_Asset.T0_Field1}
then apply your red condtion to this formula field
if isnull({vw_Asset.T0_Field1}) then CRRED else CRNOCOLOR
