vbcrlf char appears when i use it in a macro

if i use a vbcrlf in a macro a character appears in my excel file.
How can i set two strings in one cell under each other without having the vbcrlf char?

Code:

---

Cells(i, 4).Value = Cells(i, 4).Value & vbcrlf & Cells(i, 5).Value & " u."

---

oops, already found it myself

Code:

---

vblf

---

does the trick...
