Limit Advance Amount based on DFF Value.

Summary:

I would like to limit the Advance Amount based on the DFF value that I created. If the Advance Amount is more than the Spend Authorization Amount when I want to save the record, it will trigger an error message or such.

Is there any way to achieve this? I tried using Page Composer, but I cannot access the DFF from front-end side, so I cannot link the Advance Amount input to the DFF. I would appreciate that if there are workarounds to achieve this feat. Thanks.
