?Parameters from Formulas

[miked123]

1. I need to pass a formula to CR.
2. Parse the formula so that 4 parameters are initalized from within the formula.

I can only pass multiple parameters in this manner or a table since I'm using a Tool that restricts passing multi parameters.

I need to know the syntax of assigning a value to a ?parameter object.

This does not work when assigned in a formula:
?parameter1=@status

I actually pass the parameters in a table that is linked by the userID.
Thanks

I've used Crystal for over six years and have never seen a way to do this. I've just tried the following but they fail.

1. Inserting the 'BeforeReadingRecords' clause to the formula assigning a value to the parameter field
2. Using 'WhileReadingRecords' (just in case)

The error messages seem to indicate that you simply cannot assign a value to a parameter field! Steve Phillips, Crystal Consultant

Steve,
I have it working passing one parameter and a formula that sets 3 other criteria in the report.

The draw back is you have to close and go back to the calling app to reinitalize the 3 formulas, the re-open the reports again.

I know this is a problem in our tool, but I'm looking for a quick fix/workaround.

Thanks for the effort.

A parameter can't get it's input from a formula. It can ask you for input or you can pass the parameter value directly from the application.
