Invoice Help

Question

I am using LiveCycle Designer to create invoices for my small business. I used one of templates available and edited it to my needs. My problem is that I can not get it to compute sales tax. The invoice was already set up to compute everything else such as quantity, amount, and subtotal, with a grand total at the bottom. There is even spaces for sales taxes at the bottom, but I can not get it to work. Can someone tell me what I'm doing wrong, or not doing, to get this form to work. Any help will be greatly appreciated!

Hi,
when you want to create a simple CSV File from your HTML Client I would prefer using a ashx (generic handler) for this kind of things.
You can create a button on your Screen and in the execute Tap subroutine insert something like this:
myapp.yourscreen.ShowDetails_execute = function (screen) {
var paramValue = screen.anyvalue; //a possible parameter
$.ajax({
type: 'post',
data: {
oparaid: paramValue,
url: '../WebRequests/yourhandlername.ashx',
success: function success(result) {
// Show result
if (result != "") {
element.innerText = result;
else {
element.innerText = result;
In the ashx you have to make your work in the ProcessRequest Routine
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim erg As String = ""
Dim myParameter As String = ""
Try
myParameter = Convert.ToString(context.Request.Params("oparaid"))
if myParameter = "" Then
Throw New Exception("There was no parameter")
End If
Using Ctx As ServerApplicationContext = ServerApplicationContext.CreateContext()
Dim ocsvdata = Aggregate b1 As anytable In Ctx.DataWorkspace.data.table Where b1.table.Id = CInt(myParameter)
'Write CSV File
erg = "Csv File is written"
End Using
Catch ex As Exception
erg = ex.Message
End Try
context.Response.ContentType = "text/plain"
context.Response.Write(erg)
End Sub
This should be all. Translating this into C# should not be an issue.
Hope this helps
Kind Regards
