Input Boxes

I have an input boxes which I would like to only let the user enter Capital and Lower case d and c.

I have tried using the characters options in the properties menu but I am having no joy!

Any idea's?

in MX:
suppose your text box/field has the instace name t_txt:

code:

---

t_txt.restrict = "A-Z d c";

---

Thanks for that, it worked a treat!!
