Would this patch help fix my problem?

www.artio.net/support-forums/vm-invoice/...der-edit-input#34495

Yes I have version 2.0.24 of VM invoice.

My problem is being generated by the "Shipment Methods"
under: Shipment type - Tax

If I change this Tax option to "Apply no Rule" the "other Fee/Discount is not implemented but then
my total tax calculation is not correct but the final amount is.
see attached gif

Hi Maju
Did you solve the below problem?

Oddly enough I only started having this problem after doing the recent update to
VM2 v2.0.20b,

attached gif shows the duplication.

It is displaying the tax of my shipping and handling twice in the invoice, below the subtotal
line (duplicating it) but it is not, thankfully, adding it to the total.

Thanks pama,
I upgraded using the option to go from Artio server and both email and pdf invoices are being generated.

FYI pama
I had seen on the Joomla site that you said due to constant updates VM2 updates there had been some problems but you had and update for VMinvoice. However it did not show the new updates available section, I check it just to be sure I had the latest version. Not sure if you changed anything within the time I posted here? just thought you might like to know.

So thanks again, I am up and running.

It appears this is a common problem,
I purchased this only an hour ago and this has not even generated an invoice for me, I get the same problem straight away when clicking on email or pdf invoices.

Fatal error: func_get_args(): Can't be used as a function parameter in .../administrator/components/com_vminvoice/helpers/invoicehtmlparent.php on line 49

I removed the above offending line, to see what would happen and for both email and pdf invoices I then get the following:

Fatal error: Call to undefined method InvoiceHTML::sprintf() in .../administrator/components/com_vminvoice/helpers/invoicehtml.php on line 418

opening that file I find that the line is blank.

So ... without this this working this software is pretty much useless.
Right now I can not see how to use this to change the invoices info in the default VM orders info, that for a start would be a quick fix.

Hope you can help
