Of course! I've reviewed your code, found a couple of errors, and fixed them. ### What Errors Did I Find? 1. **"Amount in Words" Was Incorrect:** The function that converts the final amount into words (e.g., "One Hundred Fifty Rupees") had a small logical error. For numbers between 20 and 99, it was not calculating the "tens" part correctly. For example, it would convert `54` to `"Four"` instead of the correct `"Fifty Four"`. 2. **Incorrect Product Serial Number in Preview:** In the invoice preview, if you added several products and then deleted one from the middle, the serial numbers (`Sr.`) in the list would show a gap (e.g., 1, 3, 4...). This has been fixed so the numbers are always sequential and correct (1, 2, 3...), no matter which product you remove. I have corrected these issues in the code below. ### Corrected Code Here is the complete, error-free code. You can copy and paste this to replace your entire file. ```html
