SUMIFS dates are between or equal to specific dates

Wondering if anyone can help me please?

I am trying to get a formula to work and cannot figure out why it wont!

I am looking to add together costs if the date in which the costs occurred fall within or are equal to specific dates.

The formula I have detailed below is working for if the date of cost occurring is between the dates but I would also like it to pull through if it occurs on the same date

=SUMIFS(Table2[Total Cost of Fogging],Table2[Date of Fogging],">"&Summary!B18,Table2[Date of Fogging],"<"&Summary!C18)

I thought that by adding "=" before the ">" and after "<" this would solve the issue but it doesn't seem to work

Sorry if this has been posted before, I'm new to this forum and would greatly appreciate the help!

Yes I tried - =SUMIFS(Table2[Total Cost of Fogging],Table2[Date of Fogging],"=>"&Summary!B14,Table2[Date of Fogging],"<="&Summary!C14)

but that didn't work. So I can get it to pick up the costs if it's between the dates but not equal to!

Thank you for your help!
