3. Final Answer:

   Form fields -> Option C

3. In a no-code invoice tool, if you add 3 items priced $10, $15, and $20, what is the total invoice amount?

medium

A. $50

B. $45

C. $40

• Subtracting prices instead of adding
• Confusing total with average price

4. You created an invoice but the total amount shows zero. What is the most likely error in a no-code invoice tool?

medium

A. Saved invoice twice

B. Used too many items

C. Entered customer name incorrectly

D. Forgot to enter item prices

Solution

1. Step 1: Identify cause of zero total

   If total is zero, likely no prices were entered for items.

   Too many items or customer name errors do not affect total calculation. Saving twice does not reset total.

3. Final Answer:

   Forgot to enter item prices -> Option D

4. Quick Check:

   Missing prices cause zero total [OK]

Common Mistakes:

• Assuming customer name affects total
