Below is the HTML and the JavaScript being used to display the dropdown only if one of the options from the preceding dropdown is selected. When I select the one that is linked the following dropdown it works while when I select the second option not linked to the following dropdown and click submit, it throws the error "An invalid form control with name='AdjustmentBuyerPrice' is not focusable". Please point out the mistake that I did in my code.
