Any guidance on the following snippet of script would be appreciated. Ive created a scheduled task triggered by the change of the system tag (@UserName). The script is supposed to monitor the value of (@UserName) and write a value to an HMI tag. The first "IF" statement works but nothing that follows it.

export function Task_GetUser_Update() {
let userName = Tags("@UserName").Read();
if (userName = "String1") {
Tags("CurrentUser").Write(1);
} else if (userName === "String2") {
Tags("CurrentUser").Write(1);
} else if (userName === "String3") {
Tags("CurrentUser").Write(2);
} else if (userName === "String4") {
Tags("CurrentUser").Write(3);
} else if (userName === "String5") {
Tags("CurrentUser").Write(4);
} else {
Tags("CurrentUser").Write(0);
}
}

Thanks,
Ian
