AFTER UPDATE<\/h2>\n

You can use the unary operator. For example,<\/p>\n

+$(\"#cash\").val()\n<\/code><\/pre>\n
As in,<\/p>\n
paidSoFar = (+$(\"#cash\").val()) + (+$(\"#card\").val());\n<\/code><\/pre>\n
\n
BEFORE UPDATE<\/h2>\n
To answer your question specifically without going into details of all the other problems. In the following lines of code.<\/p>\n
function remaining() {\n  ...\n  if (paidSoFar >= totalOwed) {\n    ...\n  } else {\n    remaining = totalOwed - paidSoFar;\n    ...\n  }\n}\n<\/code><\/pre>\n
If you follow the usage of remaining<\/code>, you can clearly see that you are overwriting remaining<\/code> to a number. So, the next time you try to use remaining()<\/code>, you may be getting the following error in your JavaScript console.<\/p>\n
Uncaught TypeError: number is not a function\n<\/code><\/pre>\n
And the following usage is also worrisome.<\/p>\n
function remaining() {\n    ...\n    $(\"#changeOrRemaining\").html(remaining);\n    ...\n}\n<\/code><\/pre>\n
This one is clearly an infinite loop.<\/p>\n
Check How to open the JavaScript console in different browsers?<\/a> for details to access your browser’s console.<\/p>\n<\/p><\/div>\n
