Answer 1

Use following code in when-validate-item
declare
a_var varchar2(10);
begin
if trunc(a_var)=to_number(a_var) then
dbms_output.put_line('Corrent Phone');
else
dbms_output.put_line('Fractional part in Phone');
end if;
exception
when others then
dbms_output.put_line('alpha numberic Phone');
end;
You can replace a_var with name of ur text item
