Did you ask on youtube?
This screen was empty in your aia.
You never loaded your Spinners?
Here is where you can download a recent (monthly) csv table of currency conversion rates:
To convert a currency between two arbitrary currencies, first convert to a common currency like dollars, then convert to the desired end currency.
Remember, the opposite of multiplication is division.
You should NOT need an if/then/else branch for each and every currency.
Keep the downloaded csv table in your Media folder and load it at Screen.Initialize time.
Load your List Pickers from the table.
Sample app:

RprtRateXchg_20241001_20241231.csv (7.4 KB)
Look how short the blocks are when you switch to a table based approach.
