Hi @desiventure6,

Thanks for posting your code, but I don’t think there’s enough here to detect what’s going wrong. There are various references to variables like “evolution” and “evolution_img” that we can’t see in the code you provide, so we can’t help diagnose why the program is erroring.

Why not just combine these lines…

[lua]

local evol_img

evol_img = display.newImageRect(“Game 2.0/Play Scren/task/Avatar_Level/”…evolution…"_finish.png",evolution_img.width,evolution_img.height)

[/lua]

… into this line?

[lua]
local evol_img = display.newImageRect(“Game 2.0/Play Scren/task/Avatar_Level/”…evolution…"_finish.png",evolution_img.width,evolution_img.height)

[/lua]

Best regards,

Brent
