Re: custom rgrep with multi dirs

I have this function:

(defun xah-find-word-usage (myword)
  "Grep a dir for a word's usage."
  (interactive "sWord to search: ")
  ;;(require 'grep)
  (rgrep myword "*\\.html" "~/web/p")

However, if i call if for the first time, i get
“grep-expand-template: Wrong type argument: stringp, nil”.

But if i have used rgrep before in this session, then it works.

I guess i need the (require 'grep) but that didn't help. Any hints?
