Keep getting undefined index error, cant figure out how to declare value in the submodal window

I am a beginner in PHP and MYSQL, I really need your help. I am attempting to insert new information into the database, and installed the submodal feature to input and view customer notes. I am attempting to Insert a "New Customer" into the database, and keep getting undefined index error for the "Notes" field...I am not sure how to declare the value since I am using the submodal feature and also have an Image that the user will click on to activate the submodal. Here is the code for the table...thank you all very much!!

 <form action="<?php echo $editFormAction; ?>" method="POST" name="form1" target="_top" id="form1">
<table width="30%%" border="1">
<tr>
  <td>First Name:</td>
  <td><label for="First_Name"></label>
  <input type="text" name="First_Name" id="First_Name" /></td>
</tr>
<tr>
  <td>Last Name:</td>
  <td><label for="Last_Name"></label>
  <input type="text" name="Last_Name" id="Last_Name" /></td>
</tr>
<tr>
  <td>Address:</td>
  <td><label for="Address"></label>
  <input type="text" name="Address" id="Address" /></td>
</tr>

If it is valid for $row_Recordset1['Id'] to be unset, try doing the following:

<a href="subform.php?Id=<?php if (isset($row_Recordset1['Id'])) { echo $row_Recordset1['Id']; } ?>" class="submodal">

Did you access this page through a form? If not, $_POST does not exist. Also if there is not a field known as Notes (case sensitive - i.e. <input name="Notes">), then this field is non-existent and will throw this type of error. If it is returning to this page, check that $_POST exists with if(isset($_POST)) before trying to access the variable.

ORIGINAL ANSWER

If you are getting an undefined index error in your Notes: section, then $row_Recordset1['Id']; does not exist. Make sure that your database field is Id (case sensitive) and not ID, id, or some variation. class="submodal" looks like HTML code and should not effect this issue.
