hi.

i want to throw thw error message if the user enters the value not valid for the zregion1 of zbwcntry

and user should be able to correct it before moving ahead.

Also,iis not a mandatory field,So if it is initial,it can b blank.

but if the input doesnot lie in the range,it should give error message.

please suggest the line of code and where it is to be added.
