 when I'm trying to get the 1st word of the last para on the last frame, the script choked because there was an empty para right at the end. I put in a "try" so I could deal with one empty para, but I would like to put in a loop in case there are several empty paras.   

Jay, 

Instead of a "try" statement, you can use the "exists" event. Basically the events takes any object and will return true if the object exists and false if it doesn't exits. Here is an example: 

if (exists word 1 of myLastPara) then
     set myLastName to word 1 of myLastPara
else
     set myLastName to word 1 of paragraph -2 of myTextFrame
end if
