Find records between date range
I have a table called sales. In this table there is a field called date ( it is creation date ) . In this table I did a find to find recrds with the following date ranges
a) 6/24/2013...6/28/2013 - got the results
b) 7/1/2013...7/7/2013 - got the results
c) 6/28/2013...7/5/2013 - get a modify find box. It does not search for these dates. Why and how do I fix it.
