Your function produces an error. This works.

// ignore zeros at end too

function lastNoZero(myRange) {
    lastRow = myRange.length;
    for (; myRange[lastRow - 1] == "" || myRange[lastRow - 1] == 0 && lastRow > 0 ; lastRow--)  { 
       /*nothing to do*/ 
    }
    return myRange[lastRow - 1];
}
