Using Arrays and Validation Controls in C# ASP.NET

The part of this assignment that I'm stuck on is this: The user must enter a state abbreviation in the "State" field (which is a standard textbox). However, I'm supposed to make sure that the the characters entered in the textbox are a valid state abbreviation. So I create an array of all 50 states, and then used a custom validator to accept the user input and compare it to all 50 state abbreviations using a for loop. However, I'm getting an error that says I haven't created a definition for an event (stateArrayCheck) even though I know I have! I have a lot more work to do on this project, so this is really frustrating being stuck on this part of the assignment. Here's my code:

<html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
        <script>
            void stateArrayCheck (Object source, ServerValidateEventArgs args)
            {
                string[] states = new string[49];

                states[0] = "AL";
                states[1] = "AK";
                ...
                states[48] = "WI";
                states[49] = "WY

                for(int i=0, i <= states.count, i++)
                {
                    if(valState.text != states[i])
                    {
                        Response.Write("Please enter a valid US state.";
                    }
                }
             }
        </script>
        <style>
            #name {
                float: left;
            }
        </style>
    </head>
    <body>
        <form id="form1" runat="server">
            <div id ="name">
                <asp:Label id="lblFirstName" Text="First Name:" AssociatedControlID="txtFirstName" Runat="server" />
                <asp:TextBox id="txtFirstName" Runat="server" />
                <asp:RequiredFieldValidator id="reqFirstName" ControlToValidate="txtFirstName" Text="(Required)" Runat="server" />
            </div>
            <div>
                <asp:Label id="lastName" text="Last Name:" runat="server" />
                <asp:TextBox id="txtLastName" Runat="server" />
                <asp:RequiredFieldValidator id="reqLastName" ControlToValidate="txtLastName" Text="(Required)"Runat="server" />
                <asp:Label id="city" text="City:" runat="server" />
                <asp:TextBox id="txtCity" Runat="server" />
                <asp:RequiredFieldValidator id="reqCity" ControlToValidate="txtCity" Text="(Required)" Runat="server" />
                <asp:Label id="state" text="State:" runat="server" />
                <asp:TextBox id="valState" MaxLength="2" Width="20" Runat="server" />
                <asp:CustomValidator id="reqState" ControlToValidate="valState" OnServerValidate="stateArrayCheck" Text="(Required)" Runat="server" />
            </div>
        </form>
    </body>
</html>

I know you may not be a huge fan of validators. My teacher isn't either, but they're required for this assignment. Any help would be GREATLY appreciated. Thank you.

unless this is a typo the last line is missing a quote and semi colon

states[49] = "WY

You also declare the array for 49 elements then assign 50 elements to it.

string[] states = new string[49];

You should declare for 50 and 49 is the 50th element.

string[] states = new string[50];
