How to create grouping based on the delimited text

Hello,

I am using crystal report 9.0.

In my scenario, database field column Name Limit , returning "1:2"

In the above result, report should be grouping two times,(means detail section should print two times)

Ex: Limit = "1:2"

Print Group section Header

   print Detail section

print group Header

  print Detail section

If Limit="1:2:3" , then report should be grouping 3 times.

Ex: Limit = "1:2:3"

Print Group section Header

   print Detail section

print group Header

  print Detail section

print group Header

  print Detail section

Please help me, how to resolve this?

Thanks

SS
