Problem description

with this line of code, I want to update varTotal:

<input type="hidden" id="amount" name="amount" dmx-bind:value="(price * quantity)" dmx-bind:id="'inp_amount'+$index" dmx-on:updated="varTotal.setValue(varTotal.value + value.toNumber())">

The update to varTotal does not happen.

@ben I tried it in w6.0.0 beta8 stable and got the same NaN value for for the variable…
But I tried to add a debounce on the updated event, starting from 20 and increase.
EDIT: It works when debounce=100 and the value is updated

Thank you Tasos for putting in the time and effort to help me out.

I reverted to the stable version and even without debounce, the code does work.

I guess that App Connect 2 has not caught up yet.

Hi Ben, is this input inside a repeat region?

@ben
Is the dmx-bind:value evaluating correctly - could the price or quantity be a string? What does the element look like in the browser dev console’s HTML?

Is it possible that you post the whole code involved, as i just tested this code with an input inside a repeat region and the varTotal is updated perfectly fine.

I spent hours on the problem, left for dinner, had a nap and returned to Wappler.

Problem gone. All works as expected. Thanks all for your input in helping this codger.

Update: This is the code

            <div class="row">
                <div class="col">
