DYMANIC Parameters but in Record Formular- Help.. urgent

[sommererdbeere]

Hi,

I am having trouble with dymanic values in parameter for Crystal report 8.5.

problem:
i want to have 3 selections criteria.

1. date
2. region
3. customer

the biggest challenging and problem here is region and customer. for example: i have 3 regions: europe, asia, america

if the user choose europe, then he/she also want to choose china, but he/she only needs couple customer names for china like china_info_1, china_info 2, etc. but these customer names are imported from the database directly.. below is a simple schematic:

selection by:

1. Date
2. Region --> europe
china
- china_info_1
- china_info_2


or if he/she only select 1 region like china.. it will give the following schematic:

1. Date
2. Region --> china
3. customer

please. please please help.. i know this is very difficult.. i hope anyone can tell me any solution if u know..

thousands and millions of thank..

m

It's worse than difficult, it's impossible as Crystal doesn't support this.

What you want is not only dynamic parameters, you also want hierarchial. There is a third party product that supports this:
