X86 Assembly I want to get a number from my keyboard and compare it, after that I want to print a message

I want to get a number from my keyboard and compare it, after that I want to print a message. Here is my code...

My problem: When I get something from the keyboard, I can press any key and it still says 'PC:Salut'. The program runs without comparing. I want to press 1 and the program to know that 1 corespunds with Romana_Salut.

DATA SEGMENT

    m1 DB 'Chose one of the numbers',10,'$'
    m2 DB '1.Romana',10,'$'
    m3 DB '2.Engleza',10,'$'
    m4 DB '3.Germana',10,'$'
    m5 DB '4.Spaniola',10,'$'

    STR1 DB "ME:->$"
    STR3 DB 'PC:Salut',10,'$'
    STR4 DB 'PC:Hi',10,'$'
    STR5 DB 'PC:Bonjour',10,'$'
    STR6 DB 'PC:Guten Tag',10,'$'
    STR7 DB 'PC:Hola',10,'$'
    STR8 DB 'End',10,'$'
    LinieNoua DB 10,13,"$"
    alg DB 0

You didn't compare the character correctly:

DATA SEGMENT

    m1 DB 'Alege unul dintre numere pentru a afla cum se spune Salut in urmatoarele limbi',10,'$'
    m2 DB '1.Romana',10,'$'
    m3 DB '2.Engleza',10,'$'
    m4 DB '3.Germana',10,'$'
    m5 DB '4.Spaniola',10,'$'

    STR1 DB "ME:->$"
    STR3 DB 'PC:Salut',10,'$'
    STR4 DB 'PC:Hi',10,'$'
    STR5 DB 'PC:Bonjour',10,'$'
    STR6 DB 'PC:Guten Tag',10,'$'
    STR7 DB 'PC:Hola',10,'$'
    STR8 DB 'End',10,'$'

END START

It is tested with tasm(masm) and link in DOSBox. .....................................................................................................................................................................

I edited so it matches what I intendet for the program to be.

Thank you SonOfSun!
