My SoftewareSerial port is "not declared in this scope" compile error

You've left out the 'setup()' function and a few braces. This compiles:-

#include <SoftwareSerial.h>
SoftwareSerial myPort(10, 11); // RX, TX

void setup()
{
    pinMode(6, OUTPUT);
    myPort.begin(2400);
}

void loop()
{
    // put your main code here, to run repeatedly:

    for (int Mins = 0; Mins < 20 ; Mins++)
    {
        for (int Secs = 0; Secs < 60; Secs++)
        {
            delay (1000);
            myPort.println("Run");
            myPort.print(Mins);
            myPort.print(" Mins ");
            myPort.print(Secs);
            myPort.println(" Secs");
        }
    }
}

I'm not familiar with that serial LCD module, so I'll assume that you know what you're doing in that regard.
(I'm more familiar with parallel or I2C LCD displays.)
You might need to clear the screen between cycles of 'loop()' though, and I assume this all prints to the first line of the LCD, since you never select the second line.

I don't know what pin 6 is supposed to do. You set it as an output, but never use it.
