g_pMenuFont is a pointer of/to the type CD3Dfont, g_pCurrentMenu is a pointer of/to the type CMenuItem, and both are pointing to null.  In case the positioning of the asterick was confusing you, you can have the asterick next to the data type, in between, or next to the declared variable, though I usually just leave it next to the pointer.  (e.g. if you had char c, *p=&c; you obviously wouldn't want the asterick next to char there, so for simplicities sake I just always do it that.)

  Please help lol

  CD3DFont*            g_pMenuFont       = NULL; 
  CMenuItem*           g_pCurrentMenu    = NULL;

CD3DFont* and CMenuItem* are NOT pointers, they are
the type of the pointer variable. g_pMenuFont and
g_pCurrentMenu are the pointers, which according to
what you wrote point to nothing.

It is the same, but probably less confusing, or at
least to me, to write it this way:

CD3DFont *g_pMenuFont = NULL;
CMenuItem *g_pCurrentMenu = NULL;

//all the same
type *pointer= NULL;
type * pointer= MULL;
type* pointer= NULL;
