Error When Response.Write Javascript Alert

I'm trying to do a Response.Write to pop up a Javascript error message when the script reaches my catch block in my ASPX page (not in a code behind or a class).

Here is the code:

catch (Exception ex)
{
    Response.Write("<script language=javascript>alert('ERROR');</script>");

    //System.Windows.Forms.MessageBox.Show(ex.ToString());
}

The error message I get is: 

} expected

No idea why it's telling me I need a }. Everything has been closed, when I remove/comment out that line and put something else, I don't get any errors so obviously, it's not like I'm missing a closing } somewhere...

Why is this happening??

Problem is you probably have this statement enveloped in

<script type="text/c#">
</script>

So the 

</script>

in statement below is taken as ending the C# script block

Response.Write("<script language=javascript>alert('ERROR');</script>");

I see two options - move this logic to codebehind or escape the script to something like

Response.Write("<script language=javascript>alert('ERROR');" + "<" + "/" + "script>");

I think you are missing single quote near language attribute, Try This:

Response.Write("<script language='javascript'>alert('ERROR');</script>");

If I were you, I would use RegisterScriptBlock. please read the text and the example. I am certainly sure that is what you need
