Does the parameter accept multiple values? Or a single string of zero or more numbers?

If it accepts multiple, then it's treated as an array. I've found that if you try to reference an array, you MUST specify an index (as opposed to passing that array to other functions like split).

But if it's not an array, where does crystal tell you the problem is?

the parameter accepts multiple values of single digit numbers. I am getting the error when I try to save my selection forluma.

I get the error:

Does it highlight where the error occurred?

I am still not clear what the parameter is, but I will assume it is something like [1, 2, 3].

This is the logic you want:



Which would translate to

if count({?parameter}) > 0 then // contains at least one value

   {table.field} in {?parameter}

By default, the delimiter for the split function is a single space.
