Making a shape's color green

This might sound dumb but I couldn't get it to work. When u click on a button I want it to make shape2 green
I think it should go like this or something ( correct me if I'm wrong)

Code:

---

Shape2.FillColor = clgreen

---

Shouldn't that work, what am i doing wrong!

Code:

---

Shape2.FillColor = vbGreen

---

Remember to set the FillStyle property to Solid.
