Help with count measure (true/false expression does not specify a column)

Hi all, I am trying a measure that calculates % of valid emails. I have the column filtered in power query and outputs "Not Valid" when email does not meet a certain criteria.

% Valid Emails =
VAR Valid =
CALCULATE(
COUNT(Invoice_Tb[Customer Email (Clean)]),
SELECTEDVALUE(Invoice_Tb[Customer Email (Clean)]) <> "Not Valid"
)
VAR PercentDiv =
DIVIDE(
COUNT(Invoice_Tb[Customer Email (Clean)]),
Valid
)
RETURN
PercentDiv * 100

I keep getting the error "The True/False expression does not specify a column. Each True/False expressions used as a table filter expression must refer to exactly one column." Not sure what to do. Thanks

@abeirne hey, try this:

% Valid Emails =
VAR Valid =
CALCULATE(
COUNT(Invoice_Tb[Customer Email (Clean)]),
Invoice_Tb[Customer Email (Clean)] <> "Not Valid"
)
VAR PercentDiv =
DIVIDE(
COUNT(Invoice_Tb[Customer Email (Clean)]),
Valid
)
RETURN
PercentDiv * 100
