Passing Parameters to a Crystal Report and data from more tables

[Maria]

Hello!

I am new to Crystal reports an I have problems passing parameters form
outside to Crystal report an creating a report with data from more
than one table

This is the problem:
I have to make a report( VS.NET, C#, Web Form) with 3 parts and with
data from three tables:
1st part: all the field values form table1 coresponding to an Id (Id
is prymary key and I want to get only one row);
2nd part: multiple rows from table2 coresponding to the same Id
3th part: multiple rows from table3 coresponding to the Id
In table2 and table3 Id is foreign key
I want to pass this Id form a list/textbox on the Web form as a
parameter to my report.
I created a parameter for the report called MF_Id with default value
1001 -the value exist in table1. I
f I set the Id field to be equal to 1001 it works, but when I set it
to be equal to {?MF_Id} it dosen't work. (form Select Expert)
It dosen't work when I write
report3.Parameter_MF_Id.CurrentValues.Clear()
report.Parameter_MF_Id.CurrentValues.Add(1001)
neither.(value 1001 will be replaced with a variable later- but I
want it to work like this for now)

Could you tell me how can I fix this?

Alsow I what suggestion about how to dial with the three parts of the
report:
a record with three subrecords - each one passing the parameter Id or
a command with union of select statemens. Selecting all the tables and
all the fields with the condition that Id=1001 well the row from
table1 and the rows from table2, but the rows from table3 are not
unique (repeat the seame row ).

you need to have everything embedded in your sql statement
itself.
