end emptyOffset

OR you could do
put cr & cr into cr2
return lineoffset( cr2, (cr2 & tText & cr2)   )
Of course make the adjustment based on the correction for the number  
of lines in tText

You will know that line 1 and line -1 will always be empty.
Be careful of using
word 1 to wod -1 of tText since this trims chars that are consider  
word delimiters
item 1 to -1 of tText that considers all chars part of the item  
string, including spaces

Ahh, the joys of chunking expressions.
