Debug error when taking a string and casting it to a float with a file stream

Debug Error

Projects\Final Project\GrItem\Debug\GrItem.exe

R6010 - abort() has been called

I was going over this with a friend and it seems as though getline() is not reading anything in and thus throwing the abort error. I'm not sure why this is because I've included the textfile, with the correct name of course, in both the regular file location and the debug folder. I ask for user input and the user then inputs the name of the file they want, I do some required things behind the scenes and display the results for them in a cmd window. I've included pastebin files for both my header and cpp files because it is far to large for one post I shall, however, post the full code in the comments.

Quick Code

The problem occurs on line 159. I'm assuming once this line is fixed, line 163 will have the same problem.

    // Read regular price
    			getline(nameFile, input, '$');
    			vectorList[count].regPrice = stof(input.c_str());// Casts string to a float
    // Read sale price
    			getline(nameFile, input, '#');
    			vectorList[count].salePrice = stof(input.c_str());
