Questão Water scripts in builds other than the towers

Hello! I'm attempting to use the water tower scripts (latest version) in a sink. I have a hidden root prim that has the scripts from the towers in it.

It still only functions as a well .... no choice for adding water, 10% per withdrawal, etc. I cannot figure out what I'm doing wrong. I have the following script in it, which should be the script from the tower. Thanks!

# Can be WIND, GRID, SELF or RELAY Gets water either using Wind powered water pump, Electric pump, built in system or via another nearby storage-well respectively
MODE=SELF
#
# Level to start at on rez/hard reset
INITIAL_LEVEL=50
#
# What liquid is this system for
LIQUID=Water
#
# How much to increase/decrease level by for one 'serving'
ONE_PART=2
#
# # How many days before level drops 1 part ('evaporation')
DROP_TIME=1
#
# How often in seconds to increase level by ONE_PART if MODE=SELF
WATERTIME=300
#
# Offset to rez water buckets
REZ_POSITION=<1.0, 0.0, 0.5>
#
# Set to 0 to disable menu and just rez product on touch
MENU_MODE=1
#
# Set to 0 if you don't want to allow adding SF_WATER item via menu to top up level
ACCEPT_PRODUCT=1
#
# In RELAY mode, where to get water from
RELAY_WELL=SF Water tower
#
# Set to 1 for clouds, rain and other effects, 0 for none
WEATHER=0
#
# If WEATHER=1 set the range of the rain in m
RAIN_RADIUS=35
#
# SEA_LEVEL forces it to be at sea level to work. Can also specify item to scan for or remove/comment out if not needed
#REQUIRES=SEA_LEVEL
#
# radius to scan for REQUIRES item
#RANGE=6
#
# Default language
LANG=en-GB

That should work since you have the config set okay. Just to check, the script is called storage_well and if you edit it you should see the the version information as float VERSION = 5.1; // 27 November 2020

Also you may wish to check there is only one prim that has the script - it may be there is another prim that also has the script and settings and maybe that one is being used instead? E.G:

It's quite odd. I had the script in an invisible prim, set as the root prim. I removed the files and put in the new ones, saved it all, and restarted the object. When I went back it was the old files again. I have NO idea what happened.

I created a new prim to use as the root prim, linked it in, and deleted the old one to play it safe.

such are the oddities of opensim!
