What if the value passed in an ID Query is not a Numerical value?
Then we check to ensure it is a numerical value before allowing it to proceed.

Assign our Variables and our Values first.

The IsNumerica() function allows us to check if the value passed is a number or text value.
We are checking to see if it is NOT a number first, showing the error if it is text, and then showing the actual values if it is a numerical value.
