Sum items in a gallery that updates live

Posted on by Lewy

Hi all,

I need to add a sum column that updates as the user enters data into the gallery. Ideally once the user add new rows and enter time I would like this to update much like an excel column cell.

For example the monday column has a text box with formula in it

Sum(galleryTimeCard.AllItems,Mon)

This sums the values in the monday column but only once the output is patched. I need feedback before any patch is happened.

Summing after a patch to collection is not ideal.

The totals summing for each day currently sit outside the gallery.

what is the name of the mon text input as we can reference that?

e.g.
Sum(galleryTimeCard.AllItems,Value(MonTextInput.Text))

ThanksAJ_Z
it appears to work but the value changes to match the number I have just edited and is not the sum of all the columns.
