Currency format

[franse]

This is the expression you need:

<input id="text1" name="text1" type="text" class="form-control">

<input id="text2" name="text2" type="text" class="form-control">

<input id="text3" name="text3" type="text" class="form-control" dmx-bind:value="(text1.value.toNumber() * text2.value.toNumber()).formatCurrency('$', '.', ',', 2)">

PS1:

It seems you're using type="number" for input7 and this doesn't work.
Maybe it's related with this:

@patrick

When setting the value on a number input it will try to parse the string as a number and 1. throws an error here. This is an implementation of the browser and not something we can change.

Instead of using a number input use a standard text input.

PS2:

I can see you're using some old App connect or beta channel there with experimental features?

Take note about that when using some functions, it's better to stay on stable channel and report some bugs if you have one.

Before change anything, a friendly advice :

Backup First!
