Hi, i need some help ! Please see the following code

useRetina = true  
  
if useRetina then  
 local formNeuText = ""  
 local btOffset = -5  
 print ("btOffset: " .. btOffset)  
else  
 local formNeuText = languageTable[def\_new2]  
 local btOffset = 5  
end  
  
print ("btOffset: " .. btOffset)

the second print results in a runtime error (nil value).
Any ideas ?

Your btOffset is out of scope by the time you reach your second print statement. It’s scope is local to that first if statement block.

Change your code to this:

  
useRetina = true  
  
local btOffset = 0  
  
if useRetina then  
 local formNeuText = ""  
 btOffset = -5  
 print ("btOffset: " .. btOffset)  
else  
 local formNeuText = languageTable[def\_new2]  
 btOffset = 5  
end  
  
print ("btOffset: " .. btOffset)
