Sumif for an month to day invoice amount with date criteria

I have an Invoice Smartsheet which has invoice amount for invoices for last several months. I have to calculate month to day invoice amount. I have given the following formula:

SUMIF([Inv Amt Rs]:[Inv Amt Rs], [Inv Date]:[Inv Date] > "02/01/2018")

This evaluates to zero, even though invoice amount is there in the range.

Please help !
