Ultimate WP and A+ versions using Child Theme

Dear Support,

I cannot make this work :^(
I have this code in my child theme's functions:
function increase_capacity( $capacity, $service_id, $worker_id ) {
return 20;
add_filter( 'app_get_capacity', 'increase_capacity', 20, 3 );
We have THREE Locations: Paula, Karuna, and Budista.
Paula can accommodate only one individual when Karuna could do up to 8. Budista is for 8 max. grupal only (minimum of 6).
We have ONE FULL FLESH Service Provider available Mon. through Fri. from 10AM till 6PM to accommodate for a one on one service at Paula and/or Karuna... Tues. only for Karuna from 6 to 9PM and Thurs. only for Budista from 6 to 9PM
We have 8 Dummies for Karuna available only on Tues. from 6 to 9PM
We have 8 Dummies for Budista available only on Thurs. from 6 to 9PM
8 Dummies because it is Grupal Treatment capable of servicing 8 people at the same time :slight_smile:
The service last about 45mn. but I allow 90mn. with 10mn play to go from one location to the other.
The Problem:
Paula and Karuna appear to work fine for the individual treatments although it remains to be proven because our FULL FLESH provider cannot be at both locations at the same time... BUT... BOTH Karuna and Budista are showing at the same time when only one Service/Location is selected...
I truly hope to be clear enough with my issue... and that someone here can help me solve it :^)
We appreciate your time and knowledge always.
Best Regards,
