I need proper syntax to get the price from my inventory table and use it in calculations. Here is the method I have so far but I don't know where to start with the calculation.
public void btnItemEnter_Click(object sender, EventArgs e)
/**This event handler will look up the item and get the description
* and the price to display into the lstItemsSold box. It will also
* keep a running total in the total labels while calculatin taxes**/
// double price;
//double tax = 0.07;
//double subtotal = price + tax;
String Item = txtItem.Text;

SqlConnection Sql = new SqlConnection("Data Source=. SAMANTHAWHITAKE\\MYSQL2012; Integrated Security=true");
string ItemNumber = "SELECT ItemNumber * FROM Inventory";
SqlCommand getRecord = new SqlCommand(ItemNumber, Sql);
SqlDataReader invRecord = getRecord.ExecuteReader();
if (Item.Equals(getRecord))
string LineItem = "SELECT ItemNumber, ItemName, ItemPrice * FROM Inventory WHERE ItemNumber = '" + Item + "'";
SqlCommand getLine = new SqlCommand(LineItem, Sql);
SqlDataReader invLine = getLine.ExecuteReader();
while (invLine.Read())

I have parts produced and parts rejected options in my app. My client gave me a condition to put:

At any time parts rejected should not be less than the parts produced
You should be able to save even if the parts produced is 0*
What do I need to put the condition there to make it successful?

errorMessage.Append("Parts rejected should not be greater than or equal to parts produced." + Environment.NewLine);

this is the condition i have now i need to change it as my client requirement
