We are doing web programming in school. I am supposed to write something that will do a tooltip when you either enter an input box or roll over an input box. It is not supposed to be a javascript alert, but a tooltip. This is what I currently have:

<td><input type="input" id="fName" name="fName" OnKeypress="return isNumberKey(event)" size="5" maxlength="20" /></td>

We haven't learned JavaScript, I couldn't find anything online, and it's due tomorrow. I found some javascript that will check to make sure that a number isn't being entered into the input box. Does anyone have a script that does a tooltip? Any help would be greatly appreciated. Thanks in advance!
