Hi Bernd,
You have a syntax error on line 8 - your quoted "2014" is missing a quote.
Then, your dataCap function, having the same name as the dataCap variable,
is a problem since the function will replace the variable value. Change
it to a different name, like changeDataCap(). Like so:
var dataCap = "2014";
function changeDataCap(){
dataCap = document.getElementById("selectedYear").value;
alert('dataCap: ' + dataCap);
drawChart();
}
...
<select id="selectedYear" onchange="changeDataCap()">
...
