Styling text with bullet points
I am trying to setup a field so that when text is added each line automatically starts with a bullet point. I have been able to get some success with the following calculation:
Substitute ( Substitute ( Substitute (Feature ; "¶" ; TextFont (TextSize ( "¶l "; 7); "Wingdings") ); " "; " "); " "; " ")
[# represents bullet symbol]
However, if I go back and edit the text in that field I get double bullets appearing.eg.
# # Cat
# # Dog
# # Mouse
If I try to remove the extra bullet it just gets worse - 3 bullets appear!
Any adivce? How can I edit bulleted text without extra bullets appearing?
