It may look like I am making things difficult, but I am learning asp.net and
javascript and trying to setup some javascript variables and items from
functions.

I dumbed down the example I was looking for ( a lot ) in hopes that it makes
sense to me ( which now I think it does ), and now I can go back and look at
a more complicated example online.

Thanks,

Miro

Good that you know how it works now. Just one remark: in general there
is no need to use the Label control (for client scripting). It can be
also done in the following way

Code-behind

Protected Dim HelloWorld As String = "Hej"

ASPX

.....
<script>
var x = <%=HelloWorld %>
</script>
.....

This would "inject" the value of the HelloWorld variable (it can be a
function too) from ASP.NET

Hope this helps

Don't forget the semi-colon at the end of JavaScript lines... ;-)

....and quotes around the string.

This computer-programming thing needs so many fiddly bits, doesn't it <g>
