Hello how are you? I would like to use the (+) and (-) icons to increment the value inside my text box, the user also has the possibility to manually change it by typing the number.

I managed to do the logic on the outside putting a variable in the Default property of the text box and in the icons I just added or subtracted 1.

But when using inside the gallery all items when I click on the icons are changed and not just the "ThisItem".

What would the logic look like in this case in a gallery?

Thanks and any help will be greatly appreciated.

Rather than using a variable, you'll need to Patch the Quantity to the datasource that is used by your gallery. Something like this
// for + icon Patch( yourDataSource, ThisItem, {Quantity: Quantity + 1} ) // for - icon Patch( yourDataSource, ThisItem, {Quantity: Quantity - 1} ) // for OnChange of Text box Patch( yourDataSource, ThisItem, {Quantity: Value(TextInput1.Text) } )
