There are a few issues in the code that need to be fixed:

1. The incorrect use of commas `,` instead of multiplication operator `.^` in `x = (A ,^n);`.
2. Misplacement of `.^` instead of simply using `.^` to perform element-wise power operations.
3. Incorrect usage of power calculations (`x.^2`).
4. The calculation of energy and power should not use the `,^` which is not valid syntax.
5. The two print statements should distinguish between energy and power properly.

Here is the corrected MATLAB code:

```matlab
clear;
clc;

% Define the signal parameters
A = input('Please enter a value of A: ');

% Define the number of terms to approximate the signal
N = 1000;

n = 0:N-1;

% Compute the signal x[n] = A^n (element-wise)
x = A.^n;

% Compute the energy of the signal
energy = sum(x.^2);

% Display the energy of the discrete signal
fprintf('The energy of the discrete signal is %.4f\n', energy);

% Compute the power of the signal
power = sum(x.^2) / N;

% Display the power of the discrete signal
fprintf('The power of the discrete signal is %.4f\n', power);
```

### Explanation of Fixes:
1. **Power operation:** Replaced `A ,^ n` with `A.^n` for element-wise exponentiation.
2. **Squared operation:** Replaced `x ,^2` with `x.^2` for element-wise squaring of the signal.
3. **Energy calculation:** It now computes the sum of the squared signal values.
4. **Power calculation:** Divides the energy by the number of terms `N` to get the power.
5. **Print statements:** Ensured that the output distinguishes between energy and power.
