I cant Multiply integer from Input Field

Hello,

I have this script that gets an amount of gold and shows you how much money its worth if you convert it.

When the input field has a value it will store it as a string and the value of gold is 1000/gold bar. Then it should take the user input and multiple the 1000. However int.Parse() is not working... :/

 if(inputText.text != null)
             {
                 string amountOfGold = inputText.text;
                 int goldValue = 1000;
                 int total = goldValue * int.Parse(amountOfGold);
 
                 money.text = total.ToString();
 
                 gold.text = amountOfGold;
                 money.text = "$" + total;
             }
