Parameter Problem

[harmonycitra]

Hi everybody,

I'm using CR 9. Is there any way to set a parameter as optional?

Thanks

I don't know of a way to set a parameter optional, but you could work around the issue by having a second boolean parameter. The boolean parameter would indicate that the "optional" parameter is either given a valid value and displayed or given a null value and suppressed.

Finally I set some default value which will not affect the result.

Anyway I'll try ur idea.
