referenceing a datareport when the name is in a variable

I need to allow a user to select a datareport (to display) from a listbox.

The problem is I do not know how to reference the datareport name from a variable.

the report name is rptOne, rptTwo, rptThree, etc based on which line of the list box the user selects.

the method I want to use is rptOne.Show

How do you reference the datareport when the name is in a variable. In this case it is in listBox(listIndex)

Moved to reporting section.
