php - Trying to Insert data into mysql table and getting a parse error for unexpected end of file

I am trying to insert into a mysql table and I'm getting a
parse error for an unexpected end of file. I am using a html file with a basic form for
users to enter data. I have a php file working alongside and when a user enters data it
is failing because of a parse error. I am a beginner in php so I would appreciate any
advice.

here is my html code:

             html>
 
 
             charset="UTF-8">
 
 
 

            


            


 First
            Name:
             id="FirstName">
 
 

             for="LastName">Last Name:
             name="LastName" id="LastName">
 
 


            Address:
             name="Address" id="Address">

 

            

 City:
             type="City" name="City" id="City">
 

            

 State:
             type="State" name="State" id="State">
 

            


 Zip:

            
 

            

 Phone
            Number:
             id="PhoneNumber">
 
 

             for="Email">Email:
             id="Email">

 
 


            Pet Type:
             name="PetType" id="PetType">
 
 


            Breed:
             name="Breed" id="Breed">
 

            


             for="PetName">PetName:
             name="PetName" id="PetName">
 
 


            Neutered or Spayed:

                        id="NeuteredOrSpayed">
 
 


            Pet Birthday:
             type="PetBirthday" name="PetBirthday" id="PetBirthday">

            mysqli_connect_error());


 if( $_POST )

            {
 $con = mysql_connect("localhost","","");

 if
            (!$con)

            }

 mysql_select_db("pet_shop3",
