Hey, I need help with my program is working fine, but have some calculation issues and my reset button is not working.

Here are things to be fixed: 1. The reset button is not working. Calculate button is too long. 2. Calculations are wrong.

Thank you for everyone!

This is the pogram I wrote:

Your GUI may look like GUI in Figure 1 LI Travel Expenses Number of days on the trip: 7 Amount of airfare: Amount of car rental: Miles driven: Parking fees: Taxi fees: Conference registration: 400 Lodging charges per night: 95 600 tD ResetCalculate Expenses Figure 1 If you enter the values shown on Figure 1 and push "Calculate Expenses" button your output may look like output at Figure 2. Total expenses: $2,104.00 Allowable expenses: $2,064.00 Reimbursable expenses: $2,064.00 Amount to be paid back: $40.00 OK Figure 2
