Data Validation - Allow Certain Numbers Only

[tlc53]

Hi there,
I thought this would be quite simple but I'm having difficulty stringing it together.
In cell G30 I would like the user to be able to add 846 or 847. However, I do not want a drop down list, I would like to use Custom.
Thanks very much!!

Why not use List & un-check In-cell dropdown?

Didn't know you could do that. Thanks!!
