Checkbox Prompt

[96turnerri]

hi all, i would like a prompt to come up if the users selects a checkbox, this is what ive got so far


<script>
var whatName=prompt("Please type in your name:","");
function doName(theName){
if ((whatName != "")&&(whatName !=null)){
document.writeln("Hello "+whatName+"!")
}else{
document.writeln("Hello! You")
}
}
</script>
<form name="quotation">
<input type="checkbox" name="Calculator" onClick="doName(whatName);"> <input type="text name="Calc">

what i wish to happen is if a user clicks on this checkbox a prompt comes up they type in something and it appears in textbox

Thanks for any suggestions or help

Something like this?<form action="#">
<input type="checkbox" onclick="foo.value=prompt('Enter your name:','');" />
<input type="text" name="foo" />
</form>

Oops. Sorry, minor typo. Slight error on my part. Here you go:<form action="#">
<input type="checkbox" name="Calculator" onclick="n=prompt('Please Tell Us The Purpose The Of Calculator(s), If Possible The Equation(s) or Proccesses Of It:','');n=(n)?n:'None Entered';Other.value='Calculator Information: '+n;">
<input type="text" name="Other" />

Thanks to you and olerag, I appreciate it... I figured that would be a common problem so that's why I went into such detail -- it'll make it easier for future readers. :D
