In Crystal report document, they give the following description about how to use Count:
Count(fld, confld, cond);
* cond is a String indicating the type of grouping for condFld. You only specify this argument when condFld is a Date, Time, DateTime or Boolean field. For more information on the valid strings for this argument, see Conditions for summary functions.
Boolean conditions
* on any change
* on change to yes
* on change to no
* on every yes
* on every no
* on next is yes
* on next is no
But there is no example. Could someone give me examples about how to write those Boolean Conditions when using count function? Thanks a lot.
