How to calculate a totals field in a form with 20 currency input fields?

[UKRiggers]

I should have known that! and I’m not good when I am not well

Any guidance on the VAT part?

[Teodor]

Then the user should press either ‘VAT’ or ‘Repairer is not VAT registered’ which would then show the VAT figure in the input field next to it.

I thought this might work but doesn’t

• dmx-on:click="((vat_yes_no.value == 138 ? 0.2 : 0) * costs_cont_rep.value).formatNumber(2, “.”, “”)"

(where 138 is the value of the ‘VAT’ field)

I don’t really understand what are you trying to do?

I’m not sure what the 138 is for - I would have thought vat_yes_no.value should equal 1 or 0 perhaps, to indicate whether VAT is applicable or not. So the onclick event would set the this value and you would just use dmx-bind:value for the VAT calculations. Using an onclick event to calculate the VAT could be a problem in that it would need to be clicked again if any figures were changed. (I am not too clear on the various issus in this thread, so this might not be useful at all).

So which inputs you want to sum values of? The radio buttons or the text inputs?
If it’s the text inputs, then try something like:

repeat1.items.sum(`specialist_total.value`)

But change the main/outer repeat which you are using to repeat children, otherwise it won’t work.

@Teodor @UKRiggers, should the repeat elements have unique IDs (like below), for this solution to work? Thanks in advance.

eg, dmx-bind:id="inp_costs_input_{{specialist_id}}" id="specialist_total"
