Hello!! I have a formula in Crystal Reports 2008 where I declare some variables. The formula is:

NumberVar CarrierVATPercent;
NumberVar CarrierVATAmount;
NumberVar VATAmount;

VATAmount: = (Sum ((SSAA_IINN_00000200_A.TaxAmount), (SSAA_IINN_00000200_A.TaxValue)));
if (CarrierVATPercent = (SSAA_IINN_00000200_A.TaxValue)) then VATAmount: = VATAmount + CarrierVATAmount;

With this code I get the following error:

Error in the formula. This field name 'NumberVar CarrierVATPercent' is unknown.

Thanks for your help!!!

You gave me very good track. Apart from the initialization of variables I have discovered more things. We are feeding the report through code with a DataSet. If a report has a subreport with the same table in the subreport and there is a formula that declares a variable and then a field asigned to that variable it fails. The solution is to add the formula field in the main report. Do you know if Crystal even if you have a table that is used with two different aliases feeds with the same datatable?

Thanks for all, regards.
