I have an issue with my Countifs function. I am looking to calculate the number of entries between certain dates using the function below:

=COUNTIFS($G$80:$G$329,">="&AE103,$G$80:$G$329,"<="&AF103)+COUNTIFS($J$18:$J$51,">="&AE103,$J$18:$J$51,"<="&AF103)+COUNTIFS($J$54:$J$77,">="&AE103,$J$54:$J$77,"<="&AF103)+COUNTIFS(Table_owssvr6[Posting Date],">="&AE103,Table_owssvr6[Posting Date],"<="&AF103)

It seems to be working well except for the fact that it does not count any dates that are the same as the "less than or equal to" parameter. Is there something wrong in the function or am I missing something?
