if string cant be converted to number then tonumber returns nil and you cant compare it with a number Lazarix9 245 — 5y

I didn't test this but let's hope it works:
01 | script.Parent.BackGround2.Enter.MouseButton1Click:connect( function() |
02 | local text = script.Parent.BackGround2.OrderNumberHandler.Text |
03 | local number = tonumber(text) |
04 |
05 | if number ~= nil then |
06 |
07 | print("Number ", number) |
08 | local OrdersHandler = script.Parent.BackGround3 |
09 |
10 | if number >= 6 or not number then |
11 | script.Parent.BackGround2.Enter.Text = "Number Not found" |
12 | end |
13 | end |
14 | end) |
Why your script doesn't work:
01 | script.Parent.BackGround2.Enter.MouseButton1Click:connect( function() |
02 | local text = script.Parent.BackGround2.OrderNumberHandler.Text |
03 | local number = tonumber(text) |
04 | print("Number ", number) |
05 | local OrdersHandler = script.Parent.BackGround3 |
06 | if number >= 6 or not number then |
07 | script.Parent.BackGround2.Enter.Text = "Number Not found" |
08 | end |
09 |
10 |
11 | end) |
If a string can't be converted into a number, then tonumber() returns nil.
If you put something that isn't a number into text then an error occurs at line 6, saying that it can't compare nil to a number value. This is easily fixed by adding an if statement to check if number is equal to nil.
