SUMIFS - There's a problem with this formula

[fortnite]

For some reason, this formula:
= SUMIFS( $C$3:$C$53, INT($B$3:$B$53), INT($B3) )
gives me "There's a problem with this formula."

The parenthesis are paired, plain value (not formulas) data in b3:c53, I expect in column DailySumPrice to have repeated sum of prices for each day.

I know I can do it with helper column, but I prefer this method.

Can anybody help?

Thank you to both of you.
@Joe4: As I said, I am sorry. My intentions were for the best. Will not happen again.
@Fluff: The 0 will affect the result, the "" works - thank you
@Fluff: Your formula =MIN( FILTER(IFERROR( C3#,99999),INT( B3#)=INT(B3 )))
adapted for AVERAGE
and added # to produce spill array: =AVERAGE(FILTER(IFERROR($c3#,"" ),INT($b3#)=INT(b3#))) does not spill

No it won't, you cannot use filter like that
