Hi guys. I keep getting the followin error 'href' is null or not an object on the following line var popwin=open(imgsrc.href, "popwin", popupsetting[1]) in the code below.


<script type="text/javascript">



var dimension="5x4"
var imagepath="images/gallery/"
var href_target="new"

var popupsetting=[1, "width=500px, height=400px, scrollbars, resizable"]

var descriptionprefix=[0]

var gsortorder="desc"

var targetlinkdir="images/gallery/"


function sortbydate(a, b){
if (gsortorder=="asc")
return new Date(a[1])-new Date(b[1])
else if (gsortorder=="desc")
return new Date(b[1])-new Date(a[1])
}

if (gsortorder=="asc" || gsortorder=="desc")
galleryarray.sort(sortbydate)

var totalslots=dimension.split("x")[0]*dimension.split("x")[1]

function buildimage(i){
var imagecompletepath=(targetlinkdir!="")? targetlinkdir+galleryarray[i][0] : imagepath+galleryarray[i][0]
var tempcontainer='<a href="'+imagecompletepath+'" target="'+href_target+'" onClick="return popuplinkfunc(this)">'
tempcontainer+='<img src="'+imagepath+galleryarray[i][0]+'" title="'+galleryarray[i][0]+' ['+galleryarray[i][1]+']" />'
tempcontainer+='</a><br />'
tempcontainer+=(descriptionprefix[0]==1)? descriptionprefix[1]+(i+1) : ""
return tempcontainer
}

function jumptopage(p){
var startpoint=(p-1)*totalslots
var y=1;
for (i=0; i<totalslots; i++){
document.getElementById("slide"+i).innerHTML=(typeof galleryarray[startpoint+i]!="undefined")? buildimage(startpoint+i) : ""
}
while(document.getElementById("navlink"+y)!=null){
document.getElementById("navlink"+y).className=""
y++
}
document.getElementById("navlink"+p).className="current"
}

var curimage=0
for (y=0; y<dimension.split("x")[1]; y++){
for (x=0; x<dimension.split("x")[0]; x++){
if (curimage<galleryarray.length)
document.write('<div id="slide'+curimage+'" class="slideshow">'+buildimage(curimage)+'</div>')
curimage++
}
document.write('<br style="clear: left" />')
}

function popuplinkfunc(imgsrc){
if (popupsetting[0]==1){
var popwin=open(imgsrc.href, "popwin", popupsetting[1])
popwin.focus()
return false
}
else
return true
}

</script>


Can anyone tell me why I get this error and what needs to be rectified..?
