CloudDb error and needing help

Hey, I am making an app which connects a shopkeeper with a customer. The shopkeeper can increase/decrease a quantity, and the customer can view it. I am using CloudDB for this. I've written some code which is throwing an error on me. Please help me with some new code

You need to show your relevant blocks, code, screenshots etc.

I've added it now, please check. I'm sorry for not giving it first!

The way you are doing this available does not start off as a list.

Use the AppendValueToList block for all entries, if the tag (list) does not exist, AI2 will create it with the first list item.

That code is still giving the same error of "You can only append to a list"

show your relevant blocks now?

whats that?

this?

No, what you changed in your update_availability procedure ?
