Unable to display mail merge results using Preview Results function

Hi,

I successfully created a mail merge document that utilizes Excel for it's data source. Upon selecting the "Finish & Merge" menu option, I am able to successfully print the intended documents, however, unlike previous mail merge document I've created in the past, I am unable to use the scroll feature in the "Preview Results" ribbon to scroll through and view each merged document. In prior documents this feature has always performed perfectly. Even though I am able to successfully print, I cannot view the results of the merge. I must have done something wrong but cannot figure it out. Any assistance would be appreciated!
