This is my code. Now, I set the carousel for both the texts container and images container. The images section is working perfectly fine but the same functionality is not working for the text section. The text carousel section stops after it reaches the last part, but I want it to keep going in loop like it goes for the images. I can’t seem to find the problem.

Please help me solve this – its urgent. I need it in 6 hours. Help a bro out guys!
