Adding commands to FrameMaker 8's menus

Question

Well, I thought it was straightforward. I entered these two commands in mycustomui.cfg so I can open some reference docs:
<Add Separator4          <Menu !HelpMenu>>
        <Command _MYCharSet <Label Insert Characters Palette>
<Hypertext message openfile fminit/Plugins/MultiPageSymbolPalette.fm>>
        <Add _MYCharSet <Menu !HelpMenu>>
        <Command _MYcustomB <Label FM Escape Shortcuts>
<Hypertext message openfile help/Commands[i]_8.0p277_UKE_FDK.pdf>>
        <Add _MYcustomB <Menu !HelpMenu>>
The commands show up in the menu, but they are grayed out.
When I enter these commands as hypertext in a regular document, the files open, so I know the paths are correct.
I'm sure the fix is simple, but I can't figure it out.
Any help would be appreciated!

Answer 1

I've done more testing with FM8, FM9, and FM10.
It seems that Arnis's observation that separators can cause problems is correct. With insertion of Separator4, the new commands are grayed out. Without it, they work correctly. Both absolute and relative filenames are accepted.
Arnis is incorrect, however, that a semicolon at the start of a line comments it out.
According to "Customizing Frame Products":
      Text outside angle brackets is treated as a comment. Don’t include angle brackets in comments.
Therefore, a semicolon before the <Add Separator4 ... > line has no real effect--only the semicolon itself is ignored.
The separator is fine in FM9 and FM10.
Also, make sure your angle backets balance correctly.
