ryan,

: before writing the function declare num1
: as a variable.
:
: var num1 = "";
:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fwiw, i'd like to correct your usage of the term "declare".
declaring a variable is done by using the "var" keyword and the name of the
variable.
var foo;
your example is declaring and initializing the variable. if you simply
declare a variable without initializing it with a value, it's value is
"undefined".
var foo = 1;
good luck,
