Duh, I forgot I could set the backgroundColor of the text in the field 
without having to worry about the htmlText.  This is what I came up 
with:

put text of tTargetField into tText
put number of chars of pHiliteTerm - 1 into tLength
put 0 into tLastOffset
put offset (pHiliteTerm, tText, tLastOffset) into tOffset

repeat while tOffset <> 0
   set backgroundColor of char (tLastOffset + tOffset) to (tLastOffset + 
tOffset + tLength) of tTargetField to "yellow"
   put tLastOffset + tOffset into tLastOffset
   put offset (pHiliteTerm, tText, tLastOffset) into tOffset
end repeat

Thanks,
