Have you enabled Javascript error messages in the browser?

Typo. Change aryTimeAs to aryTimeAS.

intASHours = aryTimeAS[0]; intASHours = aryTimeAS[1];

Here you put the first value in the variable, then replaces it with the second value, making the first line useless. Also, the value you put in the variable is a string, not a number.

intAEHours = aryTimeAE[0]; intAEHours = aryTimeAE[1];

Same.

dtmAE = new Date(); dtmAE.setHours(intAEHours); dtmAE.setMinutes(intAEMinutes); dtmAE.setSeconds(intAESeconds);

You are not setting the date of the date object, so the current date is used. In the unlikely event that the date objects were created on each sides of midnight, you would get an additional 24 hours. Very nasty bug, as the error is nearly impossible to recreate.

windows.alert(intNumOfHours);

Typo. Change windows to window.

windows.event.returnValue = false;

Typo. Change windows to window. --- b { font-weight: normal; }
