I'm writing a code for Telegram Bot. I want to feed in series of images as an input. for that I'm using counter variable count = 0 in order to count the number of images. However, I obtain exception when feeding in second image and so on. Exception says my variable is being referenced as local variable, whereas I made it global.
What problem may be?
