#21

I have tried again. it does not work. what can it depend on?
maybe it depends on some missing module on the server? @Teodor

#22

Please read my previous reply:

#23

ok, how do I include it?

#24

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.

#25

ok, where do I find the component?

#26

Are you sure you have gone through the documentation before you started using Wappler?

#27

yes. I have set all 3 input box on number type. But it doen’t work

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:

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 ?

#31

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.

#32

ok, I will study again
