Software Timers period value question?

Firmware
13

Oh!

I did some changes again and tested but not working even now.
Please edit to the code to make it workable.

int value;
Timer t(value, action);
int status(String command);

void setup()
{   
    pinMode(D7, OUTPUT);
    
 //   Particle.variable("value", value); to check value of value variable in console
    Particle.function("status", status);
    
}

int status(String command) //enter value like 2000 through console to set 2 sec timer
{   
    value = command.toInt(); //convert string to int for timer
    t.start();
    return 0;
}

    void action()
{
    digitalWrite(D7, HIGH);
}
