Can someone please tell me what I'm doing wrong?

[real]

I'm trying to make a program with 5 edit boxes, and 3 buttons.

i have 5 edit boxes, and 3 buttons.
1st box = first name
2nd box = last name , these are not important

3rd box = hours worked
4th box = pay rate , basic knowledge hrs x rate = total pay, using the calculate button

5th box = total pay

1st button = calculate pay
2nd button = clear all
3rd button = exit

I would like someone to tell me what is wrong so I can learn from my mistakes and grow from there. When I compile and run the program this error comes up:

Time Card.exe - 1 error(s), 0 warning(s)

IF you have the time could you please look this over?


thanks...charles
