Another function question

ripken2 (6)
I am doing a monthly budget project for my introductory C++ course. I am stuck on figuring out how to get the computeTithing() function to send the BudgetTithing back to the getdisplay() function. I'm not sure if I'm supposed to make the call from main() or from getDisplay() or if it matters. I've tried it many different ways with many different results and am just at a loss for what to do.

So my computeTithing() function is supposed to take the income and multiply it by 0.10 and then take that number back to the getDisplay() function and insert it into the display where it says BudgetTithing. Right now it doesn't seem to be returning anything. Does anyone have any hints on what I'm doing wrong?

Interesting code
Income * 0.10 == BudgetTithing;

try this on line 81
BudgetTithing= Income * 0.10;

Thank you so much! It didn't completely fix it, but it was an error that I didn't see and helped me to figure out the rest
