I have a pre-existing crystal report and would like to be able to use multiple barcode labels as the input into a parameter that allows multiple values.

When I attempt testing this report, the report runs as soon as i scan the first barcode into the parameter.

I even attempted setting up two parameter fields to enter barcodes in and when i tested this the report ran after scanning the first barcode.

Any enlightenment pro or con would be greatly appreciated.

I have no idea how to proceed at creating a parameter that does not "pass some value". Can you direct me to information about a parameter like this?
