[QUESTION] What wrong with this "len"?

[Tokio]

i got this error, but the script working fine... -.- 
bad argument #1 to 'len' (string expected, got boolean)

how to fix this?  

code:

function currentSongName() 
local radio_title = getElementData(resourceRoot, "radio.title")
if string.len(radio_title) >= x*0.0625 then
radio_title = string.sub(radio_title, 1, 80)..".."
end
	for i, shading in pairs ( offsetShadings ) do
	dxDrawText("Radio: "..radio_title, xD+shading[1], yD+shading[2], xD, yD+textHeight, tocolor ( 0, 0, 0, 255 ), scale, font, "left", "center", false, false, true, true)
	end
	dxDrawText("Radio: #ffffff"..radio_title, xD, yD, xD, yD+textHeight, tocolor ( 70, 215, 0, 255 ), scale, font, "left", "center", false, false, true, true)
end
addEventHandler('onClientRender', root, currentSongName)

I assume you get the error message on line 3 since you never said where, if so to avoid the error message just change line 2 to this

local radio_title = getElementData(resourceRoot, "radio.title") or ""

the reason you get that error message is because whenever "radio.title" doesn't exist it returns it as false, and you're trying to get the length of a string in which it gives you that error message.

I hope it helps, I can't confirm this solves the problem, as I've run into very weird problems with Lua lately, however, it should work script-wise.

Why output the another player's music?

Because you are saving the elementData to the resource. Doing this means everyone will save the elementData to the same key in the resource overwriting the previous title.

I suggest saving the elementData to the player or if the radio has an object set it to the object/vehicle.

How?

Not sure where you're saving it, but here is how you get the data from a player as well an example of storing it, however, the storing function is client-side ONLY. If you want to save the data from a server-side script you need to replace getLocalPlayer() with the player itself.

getElementData(getLocalPlayer(), "radio.title")
setElementData(getLocalPlayer(), "radio.title", theData)
