When running the downloaded iOS app: 1. What is the value of the green `error` block? 2. What is the length of the green `rows` block? 3. Is it possible your Airtable data is set to private? ---

I’m just looking at your code and I can see a number of ambiguities. I wish you can explain them. - You are using `app variable J` in the function but not used anywhere in this function. - You are using 2 list variable without any obvious use as you are assigning one to the other without and condition or amendment. - You are testing the green `error` block inside the loop which does not make it workable. These are my observation on your shared code. ---

> [@ealalin13s68](#): > > I have reinitialise the J (replace the “J” by “j” ) Variables inside loops such as (i and j) are auto initialized and do not require any initialization blocks. Your latest code still have the `green error block` inside the loop. It should be outside the loop. The loop should be inside the condition to test the `green error block`. You do not need two lists. Add the items directly to `app variable Listof Privaty` You do not need to assign one list to another every round of the loop. ---
