Why does it becomes a nil value?

Getting Started Newbie Questions
#1

I keep getting errors about the “letter” a nil value

(letter.name was the error line)

I tried looking at the error in corona simulator output and it says “Failed to find image letters/uc/…png”

but i check the folder of my app and the folder “letter” is there, also the “uc” folder with the images inside

all named as it is “a, b ,c, … z”

anyone knows why i keep getting the error?

Thanks for any help

letter = display.newImageRect(“letters/uc/”… arr_str[i] …".png",30,30)
letter.name = arr_str[i]
letter.x = xPos; letter.y = yPos
letter.idBg = i
lettergroup:insert( letter)

Before your first line put:

print(arr\_str[i])

This will tell you what is being added to the filename string. I expect that you will discover that the array is not returning what you think it is. It’s hard to diagnose without knowing what the letter.name variable is.
