The problem is that you are apparently resistant to studying for yourself.
You will not achieve anything until you solve this problem.

A useless error description. See also
<http://jibbering.com/faq/#FAQ4_43>.
And that it failed is unlikely, since it is syntactically correct since
JavaScript 1.3 (NN 4), JScript 2.0 (NT 4), ECMAScript Ed. 3. It is more
likely that you don't know what you are doing, and therefore you have used
it wrong.
What replaces the ellipsis matters here. You may have expected `a[1]' to
be
accessed as `a1' later which is not the case. My solution provides you
with
a way to let go of several numbered variables and to use an array data
structure instead.

RTFM. The above *equals* the most simple
rowCount = rowCount + i;
or
rowCount += i;
That is, provided `i' is a number value. If it is not, you will observe
NaN
as result or string concatenation instead (e.g. rowCount === "14" if i ===
"4"). To convert a value to the number type explicitly, there are several
ways.

Should be
window.alert(rowCount);
