BricksForge loading data from the metabox

Hello, I need some advice.

I have a custom field in the Metabox, for example, product A.

For this product, I have the price from supplier A and the price from supplier B.

In ProForm,

I use select from loop to select the product, and I have assigned IDs.
In the value, I have set dynamic data for both prices.

But in the text field, when I want to call them up, I either call up both or only the first value.

Can you advise me on how I can get the price of supplier A into the first text field and the price of supplier B into the second text field?

Thank you in advance.

PS:The image shows that after selection, the values are the same, but they are different in the database.
