	Create groups for From and Time To. Place these group name in Group 2 Footer. Create three formulas 1. DeclareField formula WhilePrintingRecords; stringVar str:=""; Place the same in Group 1 header. 2. ConcatenateField formula the field in the detail section by using the formula WhilePrintingRecords; stringVar str; str:=str+ {Sheet5_.Day}; 3. DisplayDay formula Place the field in Group2 WhilePrintingRecords; stringVar str; str;

	To continue on with this same scenario... What if your data was From TimeTo Day 8:00 10:00 M 8:00 10:00 M 8:00 10:00 M 8:00 10:00 W 9:00 11:00 F How would you stop the report from duplicating the three M's like below?: 8:00 10:00 MMMW 9:00 11:00 F I have been trying to figure this out for awhile!! Thanks for your help!

	You can do one of two things. The first is use the PreviousValue() function to see if the current value equals the previous value, and if so then don't do the concatenation. The other option is to see if the last character in the string doesn't match the current value and then do the concatenation. use the same code in the previous post, but add a condtional statement before it. option 1: if {Sheet5_.Day} <> PreviousValue({Sheet5_.Day}) Then str:=str+ {Sheet5_.Day}; option 2: if Right(str,1) <> {Sheet5_.Day} then str:=str+ {Sheet5_.Day}; I have all the Crystal syntax formulas and sample code for how to use them in three chapters of my Encyclopedia book. You can find out more about my books at Amazon.com or reading the Crystal Reports eBooks online.

	That eliminated most of my duplicates. But there is one more complication. If the data is listed as below: 8:00 10:00 M 8:00 10:00 M 8:00 10:00 M 8:00 10:00 W 8:00 10:00 M 8:00 10:00 W 9:00 11:00 F How would you stop it from showing: 8:00 10:00 MWMW 9:00 11:00 F Since the comparison is to the immediate previous field it will still duplicate. Thanks!!
