Fields with conditions

Hi,

I want to create a fields with condition.

T explain it, contact form only is validate if you complete fields with a determinate code.

For example

Código de Tienda (Ejemplo: “ABCD1234”)(Ejemplo: “DEFG5678”)

Letras: * only if you put ABCD or DEFG
Dígitos: * only if you put 1243 or 5678

Is it possible with this plugin? how?

Thanks!
