Why is tonumber not converting my string?
-- SOLVED -- I had made a stupid mistake with "Pack1 = script.Parent" because the numbered TextButtons are actually script.Parent.Pack1!
Hi guys. I have this script that changes a decal depending on if a player has completed a level. All of the children of Pack1 are numbered 1 through to 12. This script has broken as I have commented down below.
Help much appreciated!
01 | while true do |
02 | wait(2) |
03 | LevelsCompleted = game.Players.LocalPlayer.LevelsCompleted |
04 | Pack1 = script.Parent:GetChildren() |
05 |
06 | for i,child in pairs(Pack1) do |
07 | Level = tonumber(child.Name) |
08 | if Level <= LevelsCompleted.Value then -- this line errors. It says "cannot compare string with a number" or something similar. |
09 | child.ImageLabel.Image = "http://www.roblox.com/asset?id=173263900" |
10 | elseif (Level + 1) == LevelsCompleted.Value then |
11 | child.ImageLabel.Image = "http://www.roblox.com/asset?id=173701607" |
12 | else |
13 | child.ImageLabel.Image = "http://www.roblox.com/asset?id=173701600" |
14 |
15 | end |
16 | end |
17 |
18 | end |

On retesting the error has changed to "attempting to compare nil with a number" (Line 8). Not sure whats going on :p MasterDaniel 320 — 10y

Check if the child's name is not a string...
01 | while true do |
02 | wait(2) |
03 | LevelsCompleted = game.Players.LocalPlayer.LevelsCompleted |
04 | Pack1 = script.Parent:GetChildren() |
05 |
06 | for i,child in pairs(Pack1) do |
07 | if tonumber(child.Name) ~= nil then --Checks if the name is not a string. |
08 | Level = tonumber(child.Name) |
09 | if Level <= LevelsCompleted.Value then -- this line errors. It says "cannot compare string with a number" or something similar. |
10 | child.ImageLabel.Image = "http://www.roblox.com/asset?id=173263900" |
11 | elseif (number + 1) == LevelsCompleted.Value then |
12 | child.ImageLabel.Image = "http://www.roblox.com/asset?id=173701607" |
13 | else |
14 | child.ImageLabel.Image = "http://www.roblox.com/asset?id=173701600" |
15 |
16 | end |
17 | end |
18 | end |

Still doesn't work :S. The childs names are 1,2,3 through to 12 (there are 12 children) but for some reason tonumber isn't converting the name from a string into a number :/ MasterDaniel 320 — 10y

Is the LevelsCompleted value a NumberValue/IntValue? Cause if it is a StringValue then you may have to change that to a number by doing tonumber(s) ROBLOXING213 130 — 10y
