Here is my code for my PTO calendar:

<asp:Wizard ID="Wizard1" runat="server" ActiveStepIndex="2" BackColor="#F7F6F3" BorderColor="#CCCCCC" BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="0.8em" Height="161px" Width="1028px">

<SideBarStyle BackColor="#7C6F57" BorderWidth="0px" Font-Size="0.9em" VerticalAlign="Top" />

Type of PTO:
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem></asp:ListItem>
<asp:ListItem>Vacation</asp:ListItem>
<asp:ListItem>Personal</asp:ListItem>
<asp:ListItem>Sick</asp:ListItem>
</asp:DropDownList>
<br />
</asp:WizardStep>
<asp:WizardStep runat="server" Title="Summary">
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>

For the last step In the summary I tried to add a field to show  a summary of the info added.

The last step Im pretty much getting a confirmation saying the info was submitted : The confirmation message will be: "Name, your request for numberOfDays type days has been received and has been forwarded to supervisorName for approval". Where the name is the name of the user, numberOfDays is the end date - start date + 1, and supervisorName is the name of the supervisor. Also it must include validation for example where end date cant be before start date.

I would appreciate any help
