There are quite a few errors... Firstly, the keyword is 'function' and not 'fuction'. Secondly, in this line:
<!---Hide from non-JavaScript browsers
//This function Displays the Daily Dinner Specials at Kelsey's Diner
The phrase "Hide from non-Javascript browsers" will be parsed as script; you can stop that with commenting, a'la:
<!---//Hide from non-JavaScript browsers
//This function Displays the Daily Dinner Specials at Kelsey's Diner
Thirdly, maybe it's just been missed in your post, but there's no calls to either function DishName or DishDesc; so, it does't matter what happens in those functions, they will never be used.
Fourthly, perhaps this is a problem with the way you've pasted the code, but there should be line breaks in there. The most important ones are the ones that follow lines of comment; without a linebreak, everything from here: "//This function Displays " to the end of the script element is a javascript comment. Otherwise, linebreaks are good practice; they make it easier for you to read your code, and certainly make it easier for other people to read your code..
Using a debugger is good advice, but most debuggers will fail at the first error, and won't give helpful feedback ( like the line number where an error occured ) if your code is on one line..
