You want something like

put STime && SAmPm into startTime
convert startTime to seconds

put ETime && EAmPm into endTime
convert endTime to seconds

-- assume Intervals is already in seconds - if not, do something here

repeat with theTime = startTime to endTime step Intervals
   put theTime into temp
   convert temp to short time
   put temp & cr after field MyTable
end repeat

Note that you can avoid worrying about which line of the table you want 
by simply putting the new time after the current contents.

If you haven't already seen them, you may find it worthwhile working 
your way through the tutorial conferences at 
http://downloads.runrev.com/section/scriptingconferences.php

The first 2 or 3 of these give you a good intro to simple scripting, and 
save you from the frustration of getting stuck. (And you'd have an idea 
of which of the later ones would help with specific topics if you needed 
them).
