Record a numeric value using a + button

MarkYoung2721 — Fri, 06 Feb 2026 11:54:51 GMT

Hi,

I have an integer field for recording the number of trees in a wood. The surveyor needs to tap a + button as they count the number of trees. At the moment only a value can be entered (I think) I don't think this is possible in field maps but wondered if anyone else has found a workaround as I don't want to use S123 as we are using Enterprise.

Thanks in advance

Hi @MarkYoung2721 ,

This should be achievable using Tasks. You can set up an Edit Action that has a calculated expression to take a field's current value (i.e. the tree count field) and add 1 to it. It would look like:

Let me know if you have any questions about getting it set up.

Chris

Not an immediate fix by any means, but I suggest filing an Idea to get a "spinner" appearance for integer questions added to the forms. The teams have to reassess the form spec for other pending changes to Field Maps so this might be the perfect time to sneak something simple into scope.

Hi Chris,

Thanks for the reply but i am using Portal 11.3 and I don't have tasks as yet.

I have implemented a bit of a convoluted way.. Create a S123 form in S123 connect, configure the appropriate integer fields as appearance: spinner hide other fields and write the values back to field maps once sent in S123. Only trouble is I can't get my S123 to download a map as it says no offline maps available

Hi,

What I ended up doing (as Field Maps and S123 integration was not working syncing offline) was to have a field where the user taps a key, be it a space bar or even IIII/ similar to 'tally marks' to count the trees. Keep these fields in one group and in another group with default state collapsed is a corresponding 'tap counter' field which counts the number of taps dynamically so the user can see how many taps/trees have been recorded. Arcade code for this which is

// Count number of characters entered in the tap field
var taps = $feature.tap_treefield1;

// If empty, return 0
if (IsEmpty(taps)) {
return 0;
}

Not ideal but the best I could come up with in 11.3
