error message

It seems that I wasn't clear in my question.
What I want is the code to produce the error message like in the picture below

Below is a sample for your perusal

//Parent's age should be 12 years more than child's age.
if Relationship(curocc()) = 4 and Age(1) < Age(curocc()) + MinAgeDiffBtwnChildAndParent then
errmsg("%s's age should be 12 years more than %s's age",strip(Name(1)),strip(Name(curocc())))
select("Correct parent's age",Age(1),"Correct child's age",Age(curocc()));

In addition to what sah said take a look at the errmsg function. The use of errmsg and select together will give you the behavior you want.

Thanks so much sah. It works.
