Items can always have paragraphs in them. Items don't end until either 
the next item delimiter is encountered or the text runs out. If the 
itemDelimiter isn't a return character, then many paragraphs can be part 
of the same item.

Like this:

   get the clickChunk
   set the itemdelimiter to numToChar(255)
   put the number of items in char 1 to (word 2 of it) of fld <fldName>

Note that the clickChunk will return 0 if the user clicks in the empty 
space after the text.

   get the clickChunk
   set the itemdelimiter to numToChar(255)
   put the number of items in char 1 to (word 2 of it) of me

Items don't end at a return character, they only end when the text runs 
out or another delimiter is returns become part of the item they are in. 
So this should work fine.
