Hi Alex,
I wish I could!  The problem is that I'm setting the textshift and
imagesource of a specific character in each line.  I tried putting
everything into a variable first but the textshift and imagesource
properties aren't available in variables.

I'm currently experimenting with putting html into a variable for all the
lines then setting the htmltext of the field to the variable.
