if condition other form

if condition other form

Hi,
I use a script condition in which if the Email of student it's founded in other form request and was authotirzed for a staff member (information in the same form) I show plain field (showing alert) and I hide a field (that suggest password, because was already comunicate in the other request). The script give no result expected.

if (Count(Comunicazione_pagamento [(Email == input.Email) && (Staff_Tecnico !=  "")])  >=  1)
{
    show plain2;
    hide Password;
}

Any help?

THanks
