Displaying a parameter based on another parameter?

[wiplash]

Using CR 11.0, how can I create a second parameter but only show it IF the value of the first parameter is a certain string?

In other words, f the value of parameter A is "xyz" do I only then want to ask the user to enter parameter B, which will be a number.

Thanks

I don't think you can. You could set up a default value, meaning that nothing extra need be entered. You could also have a formula field that checks the first parameter before deciding whether to use or show the second.
