Well if you know the formula you want to use just add it and replace the values with your inputs.
Teodor’s math is correct given the information . you are giving.
For example:
100+22%=122.00
122.00-22%=95.16
it doens’t work
see this link: https://erp.decoresin.com/app/documenti/test-iva.html
thank you
result NaN
That’s strange. It worked for me locally and I’ve just tested it on a website. I’m sure the calculations are correct. This is what I see:
You are missing required includes from your page. It’s missing the formatter js include from your head tags.
I have tried again. it does not work. what can it depend on?
maybe it depends on some missing module on the server? @Teodor
Please read my previous reply:
ok, how do I include it?
Well as any other component in Wappler - you need to use it on the page so it can include its files.
Apply some formatting through the UI.
ok, where do I find the component?
Are you sure you have gone through the documentation before you started using Wappler?
Check the tutorial I sent you PLEASE!
Changing this dropdown has nothing to do with the formatter options shown in the tutorial I posted link to.
Just to check you’re not missing something, here’s the whole page:

</body></html>ok, it works great
this was missing:
script src="…/…/dmxAppConnect/dmxFormatter/dmxFormatter.js"
why when I create a new page wappler does not include it ?
Because you need to use the FORMATTER on the page through the UI so it can include all the required files!
That is why I sent you the tutorial - please check it.
I am locking this topic as it became a huge chatroom where nobody actually reads the explanations.
ok, I will study again
