WTF is wrong with my mathematical equations in this verb?

This is the verb code, it's finding an error with my dividing on line 8

[edit] rid of the goto(I am too newbish to use it anyways, I can't use it properly :P ((Please excuse any newbishness in this))
mob
    host
        verb
            Set_Shutdown_Time()
                set category = "Host"
                var/A = input("Please insert amount of time(in minutes) until you want the server to go down.")as null|text
                if(!A)
                    return
                if(A == 0)
                    src << "The time must be greater than 0."
                var/B = A / 600 / 2 //This line
                var/C = B * 600 // And this line
                sleep(B)
                world << "The world is going down [C] minutes from now."
                sleep(B)
                world << "The world is shutting down in 10 seconds."
                sleep(10)
                world.Del()
                return


Does anyone see anything wrong with my dividing?

Also, how would I make it see if A is not a number? so I can put an if() statement in there saying if it's not a number, then goto start:

I think the first priority is to forget about the math, and get rid of that goto abuse. The goto command should not be used for simple loops.

Considering a handy cancel option would be a good idea, you should lose the loop altogether and just bail out if(!A), immediately after calling input().

Simple. You're asking the player for a text string, then later trying to divide a text string by a number. The input() that defines A should be as null|num, not as null|text.

Ok, thank you, I'll try that.

[edit]
It worked, Thank you very much.

lol! turns out I remembered the math wrong. I was thinking that Milliseconds x 600 = seconds, when it's really seconds x 600 = milliseconds( I believe it was milliseconds), So I was doing all of this unecessary stuff until just now when I realized.
