Program won't detect/use double

quete5 (17)
This program finds the area of a rectangle. Double getWidth isn't cooperating with me, keeps saying that it's incompatible with double getWidth() (line 42). What am I doing wrong? I feel like it's a syntax error but I've been flipping around different ways to do it for a while now, so I'm not really sure.

Your error messages are pretty self-explanatory.

Line 6
double getWidth; Defines a double variable

Line 42
double getWidth() Defines a double-returning function

Spot the inconsistency?


Oh and then ...

Line 58
double getWidth() Defines the entire function again

Hi,

There is a typo on line 6.

You have defined getWidth identically twice. A copy paste error?
