[Javascript] newbie question

javascript is case sensitive, and 'if' is all lowercase. This will stop your
verify function from working.
function verify() {
If (document.openp2.total.value != 'STAFF1FT');
alert ("Check your addition");
}
you don't put a semicolon after if conditions
only after commands.
this is wrong:
If (document.openp2.total.value != 'STAFF1FT');
should be:
if (document.openp2.total.value != 'STAFF1FT')
also do you want the value of document.openp2.total to be a string
'STAFF1FT'
do you mean:
if(document.openp2.total.value != document.openp2.STAFF1FT.value)
ie the value of form element STAFF1FT

I am trying to use Javascript to verify the addition in an online form.
My boss wants the user to supply the sum of several numbers and than
have the form verify the sum. I am trying to get a simple version
working before I plug it in my form. The addition works fine but I can't
get the If then statement to work.
Can you tell me what I am doing wrong?
function add() {
A = document.openp2.ALA1FT.value
B = document.openp2.MLS1FT.value
A = Number(A)
B = Number(B)
C = (A + B)
document.openp2.total.value = C
}
function verify() {
If (document.openp2.total.value != 'STAFF1FT');
alert ("Check your addition");
}
</SCRIPT>
</head>
<body>
<FORM name="openp2">
l<input type="hidden" name="total" size="3" maxlength="3">
<p>full time librarians: <input type="text" name="ALA1FT" size="3"
maxlength="3" value=""></p>
<p>part time librarians: <input type="text" name="MLS1FT" size="3"

I'm guessing that with this line:
If (document.openp2.total.value != 'STAFF1FT');
you are wanting to make sure the value of the total field is not equal to
the value of the STAFF1FT field. To do this, you need to reference that
field's value, not its name:
If (document.openp2.total.value != document.openp2.STAFF1FT.value);

Cheryl,
What type of field is total? If it is a text field then it should work, but
if it is a select then you must reference the value very differently.

Cheryl,
You've probably already gotten some solutions (I can't check my e-mail
via my regular account), but in case you haven't heard back on this,
this should work for you:
< script language="JavaScript" > < !--
function add() {
A = openp2.ALA1FT.value;
B = openp2.MLS1FT.value;
openp2.total.value = (A + B);
verify();
}
function verify() {
if (openp2.total.value != openp2.STAFF1FT.value) {
alert ("Check your addition.");
}
}
/ /-- > < /script>
The last line in your form code should omit the call to "verify()",
since that is taken care of by the call to "add()":
< input type=button name= b1 value="Submit data" onClick = add(); >

The problem with your if-statement is the ";".
If you place it at the end - after the condition - JavaScript finishes
the if-statement and the alert-statement is always(!) executed.
So you should write it this way:
if (document.openp2.total.value != 'STAFF1FT')
alert ("Check your addition");
You should also take a look at the other hints - they can also help you ;-))

Good catch Mike. I never even saw the semicolon at the end of the condition
