I can set a breakpoint on the alert th see that it does indeed get fired, but it never shows up.
function btnScan_onclick(divToRefresh)
{
TheDivToRefresh = divToRefresh;
WebTWAIN.IfShowUI = false;
IfDisableSourceAfterAcquire = true;
WebTWAIN.AcquireImage();
if (WebTWAIN.HowManyImagesInBuffer == 0){
Alert('No image was scanned');
Return();
}
} 

Open in new window

Check your javascript console output. It will tell you if you have errors. It's possible it's bombing out on something else before getting to this...especially if the javascript had a fatal exception due to missing terminators etc.

the "a" of "alert" is lowecase :

alert('No image was scanned');

function btnScan_onclick(divToRefresh)
{
TheDivToRefresh = divToRefresh;
WebTWAIN.IfShowUI = false;
IfDisableSourceAfterAcquire = true;
WebTWAIN.AcquireImage();
if (WebTWAIN.HowManyImagesInBuffer == 0){
alert('No image was scanned');
Return(); // is this a function or the keyword? all javascript keyword are lowercase : return;
}
}
