Figured out the issue. I didn't understand that when the report runs you have to click one of the text boxes along the top to view data. I guess I am used to seeing data populate when the report is ran. I changed the default Flag value to 1 so when the report runs, data is always populated for the default server and then subsequent servers as you click through them.
Thanks for your help, you may consider outlining this or defaulting the Flag to 1.
