Calculate monthly gross pay

NateE (25)
I am attempting to calculate the hours and rate for the week for four weeks and then calculate the gross pay of all four weeks for a monthly total. I am not able to get the program to calculate the monthly. Any help would be great.

//I included the variable weekly and changed the gross to monthly to make more sense. I attempted to put weekly (weekPay) to add the week pay to the month gross but calculations were off. So my overtime is not calculating and monthly gross is not adding up. Still confused on what I am doing wrong. Thank you for your helpl.

I also received a warning on line 63. Operation on monthly may be undefined.

Line 62 and line 73, both have the same type of error. You can't have 2 equal signs in the same line. Change the second equals to a +, like you have on lines 41 and 81.

line 90 should be monthly variable . Because of the loop the amount monthly doubles on each iteration , So a quick and dirty fix is to divide by 2 monthly/2.

I added a few things and overtime and regular time is calculating for the week correctly. The calculations for the month is not correct.

It seems like your headed in the right direction (although there may be some unnecessary calculations/variables in there, but we can handle that later).

Take some time and check every case, what if you work only 30 hours every week, what if you work 40 hours every week, what if you work 45 hours every week. Figure out what your answer for the weekly calculations should be and see if that is correct. Figure out what your answer for the total months calculation should be and check if that is correct. Testing each of these cases will help you narrow down the case where your calculations are not doing what you think they are doing.

Simplify as much as possible, its a lot easier to make mistakes when you make the same calculation in various places instead of just one place.
HINT: Don't update the monthly pay in each of the if/else if blocks, wait until you have calculated the weekly pay in those blocks then after just set monthly to monthly + the weekly pay just calculated.
