HOw to pass a dataset column as a parameter to Crystal?

I am using vb.net 2005 and crystal reports and I am wanting to pass a calculation I have in my select statement to crystal as a parameter.

My select is like this

Select (ks.TotWeight / 100) * price.mkprice)) As TotalPrice, ks.Pay, ......

my select contains alot of other fields + a join on the price table.

VB Code:

If Not [Parameter] = "" Then Report.SetParameterValue(0, [Parameter])

Shak,

This code sample you provided....it that within a VB.Net app or CR? Also, for the SelectionFormula....can you use an embedded SQL statement?

Thanks,

I tried that with no luck. The essential problem I am having is this:

I have 2 tables with fields that appear in my report. My select statement does on a join to have conditions met on both tables. If I run the query in Query Analyzer, it returns 1 record, like it should. One of the fields on my report is a formula.

({ks.tot_c_weight} / 100) * {price.mkprice}

Whenever I add this formula to the report, the report removes ALL data when I actually run it. If I remove the fomula from the report, then all of the data appears at runtime. I tried it by just adding any field from the Price table to the report, and it doesn't matter which field I drop onto the report, all data is removed.

This is why I was going to try to pass it as a parameter.

Any ideas what causes this? I am lost!
