Appending to a text field

You need an extra variable to sum up the initial value of the textfield and all added values, so the text in the textfield can be replaced completely.

I've attached an example in that you select animals with checkboxes. The selection is displayed in a textfield.

Hello Tim. I tried "change content" but that would replace whatever already is in the text field. What I want it to do is append to existing text. For example, you start out with a text field with a word "dog" in it, then when you click a button it would add a comma and a word "cat" to it and so on so it looks like this (dog, cat,...).

Thanks Tim! This is very helpful.

You can use the "Change content" action to get the value from an input field (or any variable) into a textfield.

Hi Nick,

good observation, the checkbox variable can have only two states, "on" (= checked) or empty (= unchecked), so "Not empty" would be the same as "Equal to on".

Hey Tim,

I noticed that for the actions of the checkbox, you had it set to var equal to on.

Is there any difference in functionality to having this as checkbox is not empty?

I've tested and from what I can see it works the same, but as your experience is far greater than mine, I thought I'd ask the question.
