How to create code or this type?

My form to survey the bird, butterfly, etc

For example: I am entering the abundance of a bird and I am seeing the bird again this time the abundance number should add with previous count.

Good morning @Thalavaipandi and welcome to the ODK's community's forum.

When you'll get a chance please take some time to introduce yourself here and don't hesitate to use a real photo for you profile.

We faced the same need in the past and we found a convenient workaround for the enumerators, consisting in counting the number of time each species was selected. The limitation is that its works with a closed option 'species) list
There is no + or - button for each species but simply show the final count for each species was sufficient.

Here is the form, please share any though or improvement :wink:

Probably it would be improved and more generic but for "little" closed species lists it works fine.
