BigIP Report Old

Hi, any idea about this error?

Also, how can I view the report in the browser, sorry I'm new to this.

The variable '$Global:HTML' cannot be retrieved because it has not been set.
At D:\*\bigipreport\script\bigipreport-5.0.9.ps1:2017 char:17
+     $HTMLContent = $Global:HTML.ToString();
+                    ~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (Global:HTML:String) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined

I am using xampp by the way, and here are the other result when I ran the script, I'm trying to view it from here:
