weird problem checking element data

[Castillo]

hey, i got a really weird bug O_o, check this:

songName = getElementData(getLocalPlayer(),"next_song") 
if not tostring(songName) == "none" then 

this is suposed to check if songName is not = "none" well, i have no idea why but my "next_song" element data is "music3.mp3" and it still not working its like he still thinking my element data is "none"

if someone know what is causing this please reply, thanks.

What is getElementData ?

Precedency, when you're unsure which expressions get evaluated first use paranthesis.

"not string" will always be false

what do you mean norby?

if tostring(songName) ~= "none" then

Sorry I was editing my post read again.

wait, i think when i used ~= i was doing if not tostring(songName) ~= "none" then and this is wrong (if i'm right)

now i'm testing with: if tostring(songName) ~= "none" then

Edit: correct, now is working fine, thank for the help .
