How to make "et al" appear in in-text citations in APA 6th

Many thanks for your reply. I had not actually written each author on one line, but instead separated them with commas. Splitting them to one line per author now created a new problem: Endnote now cites all authors in the text. So now my citations say (Oldham, Cummings, Mischel, Schmidtke, & Zhou, 1995) - instead of (Oldham, 1995). Obviously made a difference, but still no et al… 

Have attached the things you required. I wish I was able to upgrade, but I am just a fairly poor PhD student studying a distance course, so I probably have to try and sort it out without the upgrade, unfortunately.  

Let me know if you have any other ideas, given the new circumstances above. 

Thanks again!
