Amy tests her form by entering 6 for the month and 31 for the day. What bug does she find?

June 31 should be an invalid date, because April, June, September, and November only have 30 days. She needs to validate the day and month in combination!

• Add a conditional that checks if the day is 31 for the months with only 30 days.

• If the combination is invalid, print the message: Error. Day must be within the month.

Pay attention to your compound condition's order of operations - you may need parentheses here! You can ignore February for now.

Make sure to print the exact error message provided.
