Member variable exists, but program refuses to see it.

msulli1355 (54)
I am working through a DirectX game tutorial on YouTube. I was doing the homework for Tutorial 10, and I declared a member variable in the Game class called yPos, but Visual Studio insists that it doesn't exist. The other three variables I declare (in the class file) and use (in the member function) exist, but Visual Studio has a problem with this one variable. Why?

I've encountered this problem many many times in the past. We used to refer to this years ago as an IVI error. In the past, I've tried many things such as renaming the variable to something else, but it rarely works. Usually, I get bored and give up. I'm trying very hard not to do that this time. Thank you in advance for anyone who can give any information toward resolving this issue.

The only problem that I see is a closing parenthesis that is missing on line 113.

The first point yPos is throwing the error is on 111. I do see the missing closing paren on 113. Thank you for that. I re-downloaded his framework and recreated the program, and it worked. I only had to add xPos, yPos, width and height to the header file, and then mess with the loops in ComposeFrame. I would still like to know why yPos was reporting as undefined, so I'll leave this thread open...
