Attempt to index nil with number

so, im making a tower defense game, and im trying to make the towers be able to be upgraded, i have all the data about what the range, firerate and damage the towers should have when they get upgraded, but i just cant figure out how to set them. theese are the lines of code that set the range, damage and firerate to the ones from the module:

tower.Configuration.Range.Value = towerupdata[tower.Parent.Name][level].Range
tower.Configuration.Damage.Value = towerupdata[tower.Parent.Name][level].Damage
tower.Configuration.Firerate.Value = towerupdata[tower.Parent.Name][level].Firerate

i keep getting the error:

Attempt to index nil with number

i am confused

With this amount of data, I can’t really be very helpful.

Could you share additional details, such as a where you created the values.

the level value is a value sent by the client, aswell as the tower value which is a object value that is set to the towers model by the server, and towerupdata is the tower upgrade data module

#4

I assume the error is referring to one of the configuration variables not existing?

You could try to check that the names are written correctly.

#5

no, they are all named correctly

#6

Did you say that the variables were “Object Values”?

#7

the range, firerate and damage values are number values, the only object value is the tower value, which is sent to the server by the client

#8

Could it be, that you meant to say:

tower.Parent.Configuration.Range.Value = number

Instead of:

tower.Configuration.Range.Value = number
#9

The error you’re getting implies that the towerupdata doesn’t have an index of the tower’s name.

#10

no, the tower value is the towers model, not the tower

#11

but i checked, and it does have the towers name

#12

Have you tried debugging with print statements? Something like

print(towerupdata[tower.Parent.Name]);
tower.Configuration.Range.Value = towerupdata[tower.Parent.Name][level].Range
tower.Configuration.Damage.Value = towerupdata[tower.Parent.Name][level].Damage
tower.Configuration.Firerate.Value = towerupdata[tower.Parent.Name][level].Firerate

Might help if it prints nil

#13

it does print nil, but on the module, it says the name of the tower, but i did set the tower value to the towers model on the server

#14

Then that’s the problem. try

print(tower.Parent.Name)

See if there’s a typo or something like that

#15

it prints nil and the towers name

#16

So that means that the tower’s name doesn’t exist in the towerupdata, are you sure it’s in there? Send the code snippet of where it is in the module.

#17

here it is:

module.Data = {
	["Gunner"] = {
		["Level1"] = {
			["Range"] = 14,
			["Damage"] = 1,
			["Firerate"] = 1.7,
		}
	}
}
#18

Is towerupdata assigned to module.Data?

#19

You could try and print the value from the table:

print(towerupdata[tower.Parent.Name][level].Range)
#20

no it isnt, is that why?
