I have a report in which I am needing to display a parameter in the header.

The parameter is a dynamic list box allowing multiple selections. Multi-dimensional array?

Placing a dynamic text box in my report header with the following expression results in "null" being output when it is, in fact, not null:

params["parameterName"].displayText
Using the following code produces numeric output (as expected)

params["parameterName"].value
How can I display the actual associated text(s) of the parameter selection(s) made at run-time?

hi. I think I can help you.
look:
1. you create a new parameter. and dont fill fields (in example I created ListBox)
2. you need to create scripts to your parameter example getSelectionValueList and getDefaultValueList
getSelectionValueList script
var arr =[]
arr[0]=1
arr[1]=2
arr[2]=3
arr[3]=4
arr;

getDefaultValueList(not required)
var arr = []
arr[0]=1

and now you can get your parameter but you must remember than you get object
in any script you can get parameter
something like this:
params["new"].value[0]
write me if you need help
