Hi Himanshu,
I wonder how you create your query with dynamic request of cartons (3 or 1 or 10). How did you filter your records ??
If you wanna make Crystal Parameters you need to define before the generation of report. CR cannot create Parameters on fly.
One thing may be you can do, take input with comma separated values and break them.
AAA,ZZZ,TTT,KK
I dont thing I'm making any sense
