Blocks (stuck, API) - please help!

Hello guys,

I’m new here only been few days on Thunkable, and I’m trying to create a Chatscreen where I can communicate with AI. When I test on Preview, I do see my text when I send it, but I don’t see GPT response.

These are all the blocks I have that I can share as screenshot.


I’m having issues with the 1 and 2 I highlighted in yellow. Do you see any problems in my blocks why GPT response is not showing when I send my text on Preview?

ChatGPT said I should replace my 1 with the 1 block in the below screenshot. Please let me know if the below makes any sense, or should I better keep the original 1 in the above screenshot.

If anyone can kindly tell me what is wrong with my blocks, I’d really appreciate, thanks
