R-squares for cross-sectional models are typically much lower than R-squares for time-series models. The X and Y ranges must contain the same number of rows, all numeric data, no missing values. To obtain a more conventional demand equation, invert your equation, solving for intercept and slope coefficients a and b, where Quantity = a + b*Price. Can you help?
