Description

When using edit gui of player, nothing happens.

Steps to Reproduce

`function tagsGUI(p: player, page: integer=1):
create a gui with chest inventory with 6 rows named "Tags":
make gui slots (integers between 0 to 53) with black stained glass pane named "&8"
make gui slots (integers between 10 and 16 and integers between 19 and 25 and integers between 28 and 34 and integers between 37 and 43) with stone button named "&8"
if {_page} is 1:
make gui slot 47 with red dye named "&aNo previous pages"
else:
make gui slot 47 with arrow named "&aPrevious Page":
tagsGUI({_p}, ({_page} - 1))
if size of {reactions::messages::register::%{_category}%::*} > 28:
make gui slot 51 with arrow named "&aNext Page":
tagsGUI({_p}, ({_page} + 1))
else:
make gui slot 51 with red dye named "&aNo more pages"
make gui slot 49 with barrier named "&aBack":
close {_p}'s inventory
set {_start_index} to 1 + (-28 + (28 * {_page}))
set {_end_index} to {_page} * 28
set {_slot} to 10
loop all integers between {_start_index} and {_end_index}:
set {_id} to loop-value
exit loop if {-tags::register::%{_id}%} is not set
showTag({_p}, {_id}, {_slot})
add 1 to {_slot}
if {_slot} = (17, 26, or 35):
add 2 to {_slot}
else if {_slot} = 44:
exit loop
open the created gui to {_p}

function showTag(p: player, id: integer, slot: integer):
edit gui of {_p}:
set {_tag} to name tag named "&x&F&F&1&3&6&9ᴛᴀɢ ᴘʀᴇᴠɪᴇᴡ"
add "&8" and "&x&F&F&1&3&6&9• %colored prefix of {_p}%&r%{-tags::register::%{_id}%::tag}% &r&f%{_p}% &8» %{stats::chatcolor::%{_p}'s uuid%} ? "&f"%Hi" to lore of {_tag}
add "&8" and "&x&F&F&1&3&6&9ʀɪɢʜᴛ ᴄʟɪᴄᴋ ᴛᴏ ᴇǫᴜɪᴘ " to lore of {_tag}
if {_p} has permission "tags.%{-tags::register::%{_id}%::uncolored-tag}%":
make gui slot {_slot} with {_tag}:
setTag({_p}, {_id})
close {_p}'s inventory
send "{@Prefix} You've selected the tag %{-tags::register::%{_id}%::tag}%&f."`

Expected Behavior

To set the slot to a name tag for the tags
