Hi guys Greeting

I am using SQL and VB.NET 2017. I have 2 buttons on a form1, (Add Save), the procedure is almost similar. Add a new record and save an edited record. I have a textbox "Email" in both buttons, which is the problem. I can not change the name because there is only one field in my table with the name Email. I show you the code of both buttons, Add and Save. I have no more ideas on how to fix it. I have tried many times in different ways. I had to declare global the textbox, declare friend, publics, and nothing fixed it, that is why I need your help, because you're a professional. This problem arises after changing the name of a field in my database table. The field was before "Interested" and is now "Email". Here is my code, very similar to the add button. Thank you, Blessing guys!

Private Sub btnSave_Click(sender As Object, e As EventArgs) Handles BtnSave.Click
Dim query As String = "INSERT INTO Citas (ID, Customer, Email, Contact, Telephone, Company, & _
Address, AppoDate, AppoTime, About, Solution, NextDate, NextTime) VALUES (@ID, @Customer, @Email , & _
@Contact, @Telephone, @Company, @Address, @AppoDate, @AppoTime, @About, @Solution, @NextDate, @NextTime)"
Dim command As New SqlCommand(query, connection)
command.Parameters.AddWithValue("@ID", txtID.Text)
command.Parameters.AddWithValue("@Customer", txtCustomer.Text)
command.Parameters.AddWithValue("@Email", txtEmail.Text)
command.Parameters.AddWithValue("@Contact", txtContact.Text)
command.Parameters.AddWithValue("@Telephone", txtTelephone.Text)
command.Parameters.AddWithValue("@Company", txtCompany.Text)
command.Parameters.AddWithValue("@Address", txtAddress.Text)
command.Parameters.AddWithValue("@AppoDate", txtAppoDate.Text)
command.Parameters.AddWithValue("@AppoTime", txtAppoTime.Text)
command.Parameters.AddWithValue("@ABout", txtAbout.Text)
command.Parameters.AddWithValue("@Solution", txtSolution.Text)
command.Parameters.AddWithValue("@NextDate", txtNextDate.Text)
command.Parameters.AddWithValue("@NextTime", txtNextTime.Text)

connection.Open()
command.ExecuteNonQuery()
connection.Close()

MessageBox.Show("Record Saved!")
LoadData()
End Sub
