Here are some guidelines how to name objects, IDs, flexgrid areas names, styles in Style Manager, etc:
1. Do not use spaces, '&', '+', '-', '!', '?', dots, quotes, brackets or other special characters in the name, keep them simple like:
"Image001"
or
"index_image001"
or
"This_is_and_image"
2. Use underscores to connect words.
Important: do not use dashes because this will break JavaScript functionality!
3. Do not start names with a number '123name' is not valid. Instead use 'name123'
4. The ID may not be empty.
Note that these are standard HTML rules.
