Formula Parameter Array Subscript 2

[omoralez]

I need to display the parm values user selected in the Heading of a report. Using Crystal 11.5 I have parameter option for multiple values, so 1 to 4 possiblities. I need to convert the numberic value parm to alpha value equalivant in the header. I receive formula error: This array must be subscripted. For example: Array

I am not sure how the parameter handles the array of values when any combination of 1 to 4 could be selected.

Parm export:
%%%%ShowDescOnly 0
1 Other
2 Aggression
3 Medical
4 Theft/Vandalism

You can use a formula like this:

whileprintingrecords;
numbervar i;
numbervar j := ubound({?Parm});
stringvar x;
for i := 1 to j do (
x := x + (
select {?Parm}
case 1 : "Other"
case 2 : "Aggression"
case 3 : "Medical"
case 4 : "Theft/Vandalism"
) + ", "
);
left(x,len(x)-2)
