Your question is better suited to the InDesing forum, which deals with general InDesign-related issues. This forum is intended mainly to deal with issues arising from the Getting Started video tutorial on creating a brochure in InDesign CC.
I hope you find the help you need there. I'm moving it this for you.
When you have a font for the bullet, create a character style for that bullet, the create a paragraph style, go the style definition to to numbering & bullets, select that font, character style and glyph and set it as part of the Paragraph style. Use that aragraph style for bullets.
BTW. Any text formatting should be done via paragraph style. Not even one space should be done without style.
If you meant "IndyFont" (not "IndyScript" ), can you please clarify
... but it doesn't work on this version of Indesign.
As far as I am aware, it ought to work on CC.
I'm not native English speaking, please explain what do you mean by "making a bullet". Bullet point numbering is a style property and not "made". So you seem to refer to something else.
It sounds like Rebecca is trying to create a custom glyph to use as a bullet (I've done this for a couple of clients, myself, using IndyFont). You can use any glyph you like as a bullet in the automatic bulleted list feature, but you have to have a glyph first.
