Can't use Find function in formula

Can't use Find function After set a formula "=Sheet1!A1" on Sheet2
e.g. input 123 on the find function, can't show a result

Its not entirely clear what you want, or if you are using the find function (like the sum function) or edit_find. So it is hard to give a good answer, you need to give more explaination. However if it is the latter are you on the sheet you are searching for the result on, and is it serching forumulas in the lookin box and you want values.
