[SalesForce] Javascript Uncaught ReferenceError: createLineItem is not defined

I keep getting this Uncaught ReferenceError: createLineItem is not defined for this line of code. It comes up in the console whenever I click on the "Create Line Item" button. I'm super uneducated with coding (slowly trying to learn) and I can't seem to figure out what the issue is.

Here is the code:

<apex:remoteObjects >
    <apex:remoteObjectModel name="Line_Items__c" fields="Id,Amount__c,Date_of_Transaction__c,Description__c,Individual_Account__c,P_Card_Expense__c,Stage__c,RecordTypeId"/>
</apex:remoteObjects>

<div class="mypage">
Amount:
<input type="text" id="amount"/>
Date of Transaction:
<input type="date" id="date"/>
P-Card Expense?:
<input type="checkbox" id="pcard"/>
Description:
<input type="text" id="description"/>
<button onclick="createLineItem()">Create Line Item</button>
</div>

<script>
function createLineItem(){
    var LineItemAmount = document.getElementById("amount").value;
    var LineItemDate = document.getElementById("date").value;
    var LineItemPCard = document.getElementById("pcard").value;
    var LineItemDescription = document.getElementById("description").value;
    var LineItemRecordType = "012o0000000pnHd";
    var LineItemAccount = {!Individual_Account__c.Id};
    var LineItemStage = "Pending Hard Copy";
    var LineItem = new SObjectModel.LineItem();
LineItem.create({Amount__c: LineItemAmount}, function(error, records) {
    if (error) {
        alert(error.message);
    } else {
        sforce.one.navigateToSObject(records[0]);
    }
});
};
</script>

Any help is appreciated!
