Problem keeping variable's value...

[someoneelse]

I have a (probably stupid) question I hope someone can help me with.. So, I set a variaible beased on a form in put in the code behind, but then, a few lines down when I go to call it , it has a undefinded value. I don't understand.. Below is the code: The problem is that when i try to reference theamount on the line I marked "PROBLEM HERE" is that when I call the API, the value for theamount is undefinded.. even though it should have a value, and does above...

please help if you can... right now i have 5 if statements with the code in all, when i only need one and the amt value set above it... ERGH...

You are declaring your variable inside the curly brackets. This is the scope of the variable.

Move it onto line 25 with

string theamount;

then assign it in your if statements as you are but remove the "var "

[someoneelse]

but i need to set the value based on the returned value of the var pt.TOString()...

based on a value, i need to charge either 10, 20, 30, 40, 50 etc.

so i need an IF ELSE statement to determine the amount to be charged before i pass values off the the ecommerce api

[DaveAmour]

Thats ok but variables have scope. In C# if you declare a variable inside { } then it can only be used there. You need to declare it elsewhere as below:

using System;
using System.Web.UI.WebControls;
using System.Net.Mail;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Net;
using System.IO;

public partial class SendMail : System.Web.UI.Page

    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            Response.Write("<br>Page has been posted back.");

            //send payment info to api, send them an email, go to thank you page

            var ccex = Request.Form["ExpMon"] + Request.Form["ExpYear"];
            var date1 = System.DateTime.Now.ToString();
            var pt = Request.Form["plantype"];
            string theamount;

            Response.Write("<BR>ccex = " + ccex);

            Response.Write("pt.ToString() = " + pt.ToString());

            if (pt.ToString() == "Gold")
            {
                theamount = "150.10";
            }
            else
            {
                theamount = "205.08";
            }

            String post_url = "XXX/transact.dll";

            Dictionary<string, string> post_values = new Dictionary<string, string>();

            post_values.Add("x_login", "XXX");
            post_values.Add("x_tran_key", "XXX");
            post_values.Add("x_delim_data", "TRUE");
            post_values.Add("x_delim_char", "|");
            post_values.Add("x_relay_response", "FALSE");

            post_values.Add("x_type", "AUTH_CAPTURE");
            post_values.Add("x_method", "CC");
            post_values.Add("x_card_num", Request.Form["ccnum"]);
            post_values.Add("x_exp_date", ccex);

            post_values.Add("x_amount", theamount);

            post_values.Add("x_description", "Plan Purchase: " + Request.Form["plan"] + ": " + Request.Form["plantype"]);

            post_values.Add("x_first_name", Request.Form["fname"]);
            post_values.Add("x_last_name", Request.Form["lname"]);
            post_values.Add("x_address", Request.Form["addr"]);
            post_values.Add("x_email", Request.Form["emaila"]);
            post_values.Add("x_state", Request.Form["state"]);
            post_values.Add("x_zip", Request.Form["zip"]);
        }
    }
}
