I saw the post Making Excel Services UDFs work on Excel 2007 - Part 1.
The fourth step said: In
Excel 2007 use the File menu to choose the “Excel Options” button. In
the dialog that comes up, choose the “Add-Ins” section and at the
bottom, make sure “Excel Add-ins” is selected in the combo box at the
bottom of the dialog and click “Go”.
But i can't find the File menu and Excel Options in my excel 2007.
could some one post the screen short of them
thanks

The File menu is that round button with the Office logo at the top right corner of the application.
If you press it, you should see an "Options" button at its bottom.

File menu: use the Office button, located at the top left of the Excel window. Keyboard: alt+f.
Excel Options button will be located at the bottom of the File menu.

Yes, this was old / internal terminology that was used here. The "File menu" is now known as the Office menu. It is outside the ribbon, the one that opens when you click the big round button with the Office icon at the top left. In the menu, at the very bottom, you will see the Excel Options button. The rest of the instructions in the post should be clear now.
