I'm quite sure this is the same problem as in the previous bug#78156
which you reported.

Moreover, given this:

> Debugger entered--Lisp error: (void-variable number)
>   (* 7 number)
>   (progn (* 7 number))
>   eval((progn (* 7 number)) t)

it looks like you didn't even install the new definition of the
multiply-by-seven function, because Emacs is still using the old
definition.

These are all user mistakes typical for a newcomer to Emacs Lisp.

There's nothing wrong with reporting these issues and asking for help
and advice, but this list is not the proper forum for that.  Given
your level of knowledge of Emacs Lisp, may I suggest that you instead
post to the help-gnu-emacs <at> gnu.org mailing list, whose purpose is
explicitly to help newcomers to Emacs?  If the discussion on that list
indicates that there's a real bug in Emacs or its documentation,
please submit a bug report with all the details using report-emacs-bug.

Thanks.

Hi,

Thanks I was learning elisp but the out was not as I expected on the
Android. I was testing with GNU emacs and sourceforge versions but it gave
the same result.

Thank you I will just have to test again and make a note of it.
