Pretty simple. I'm putting in tonumber(x), the program goes through, then when I come to the main while loop of my program, which is locationX < x, it says something along the lines of "attempt to compare number to string; got string", something like that. For reference, locationX was a variable that I initially declared as a number and x is a variable that was entered by the user and is supposed to be converted to a string from a number.

Are you using
The tonumber function will return the value converted to a number (or nil if it can't be converted). So, you have to store that return value somewhere.
x = tonumber(x)or just
tonumber(x)
