Why am I getting an Arguement Out of Range error?

[Fuzz13]

I'm using a timer from the timer class. There is a combobox with minute, hour, and day inside of it. The timer calls my GetTicks() method where if-thens are used so that based on the word in the combo box being displayed (combobox.text) an int value is returned:

Clock.Interval = GetTimeInTicks(); 
Clock.Tick += new EventHandler(TimerEventProcessor);
Clock.Start();

private int GetTimeInTicks()
        {

            string temp = Properties.Settings.Default.TimeMeasure;
            int minute = 60000,
                hour = 3600000,
                day = 86400000;

            if (temp == "Minute")
            {
                return minute;//number of ticks in a minute
            }
            else if (temp == "Hour")
            {
                return hour;//number of ticks in an hour
            }
            else if (temp == "Day")
            {
                return day;//number of ticks in a day
            }                     
            else
            {
                return 0;
            }
        }

For a time it was working fine, then I did something and now it feeds me an ArgumentOutOfRa nge error.

When I debug it takes me directly to my line:

Clock.Interval = GetTimeInTicks();

and tells me to make sure my numbers are valid.
If I hard code an interval value such as:

Clock.Interval = 10000;

The program runs and works properly, so it seems the problem is occuring when calling my GetTicks method, but I can't understand why.

The problem turned out to be that you can NOT have your timer.interval = 0; that was the out of range argument. I turned the default value to 1000 and then ran a test that says, if value is 1000 ignore everything until changed.
