Duplicating Segment

[mystik1]

I have three unique segments in my video. I have duplicated a segment several times, but when I export, it is only playing the three unique segments. I am guessing that is because the duplicated segments all have the same time in the file. I know this must be the simplest thing, and sorry to waste someone's time, but how to I get it to actually play the duplicates one after another? Thank you!
