Did I mess something up here?

I finished another part of my code and I dont understand what the output means by cannot find symbol. Did I code something wrong here? Please help, the part that's the issue is the non-commented code towards bottom https://code.sololearn.com/cXm0btZi9v6D/?ref=app

I just fixed it so you can run it with my inputs to see the output. I dont understand because it says the error is on line 77. Which is in comments..

It works, what did you change if I may ask? The only issue is on line 147. It didnt assign 'double lastpnlfc' to the value of 'lastpanelwidth + foam + 0.5

I think the problem was that you were calling a local variable outside its local environment, this returns the 'symbol not found' error which basicly means you tried to use a variable that wasn't declared. I haven't read the whole code so I might be wrong

Declare every variable right after main() or declare them with the inputs. You also have to get rid of most of the 'double' declarations, since they are already declared

double lastpnlfc = 0; double lastpnlbk = 0; double samevinylsizes = 0; double firstpanelvelcro = 0; These are variables defined before their usage if(panels == 1) { samevinylsizes = 0; } else if(panels == 3) { samevinylsizes = 4; } else if(panels == 5) { samevinylsizes = 8; } else if(panels == 7) { samevinylsizes = 12; } Notice how there aren't any double declarations, this is because we defined them before and thus don't need another declaration You defined a diffrent variable every time you checked the if's, these are local variables and don't work outside their curly brackets

Lastpnlfc is autodefined as 0. This changes on line 141, but this line is never run because lastpnlwidth equals 24. So lastpnlfc stays 0 has it to be 26.5?
