Wrong syntax?

Hi

I have put in some code in "on user input", but my "last" else if (input.replorob == "Select"), does not work in the application.

Do I have to write something else?

see full code;

if (input.replorob == "Yes")
{
show plain5;
show stock_old;
show stock_scrap;
show stock_transfered;
show replaceold;
show replacenew;
}
else if (input.replorob == "No")
{
hide plain5;
hide stock_old;
hide stock_scrap;
hide stock_transfered;
hide replaceold;
hide replacenew;
}
else if (input.replorob == "Select")
{
hide plain5;
hide stock_old;
hide stock_scrap;
hide stock_transfered;
hide replaceold;
hide replacenew;
}
