how can I fix a problem using the Elseif construct in App designer?

hi everybody. i'm trying to develop an app that localize points in a fixed volume. the problem is caused by a button callback that include an "If elseif loop" as written below.

this problem is caused by an update of the positions of sensor. this cause the problem of the wrong localization until i press two times the button "localize" (the code is shown below).

the first part of the cose use 5 sensors, while the second uses 8 sensors and the last one (not shown in the code below) uses 9 sensors. the position of the sensor can change and if I use the 8 and 9 configuration (with changed coordinates of the sensors) i have the problem explained while for the configuration with 5 sensors all the code work perfectly.

i think that the problem is inside the Elseif Operation but i cannot fix it.

any tips for alternative form or to avoid the if else loop?
