Failed to run test due to unknown error: Need help!

I guess you are trying to get the page load time with this function. right?
But what I am not able to understand here is why do you need to call the same function twice in your script.

Code:

Call CheckLoadTime("Maps","Google Maps","Google Maps")
msgbox CheckLoadTime(LnkName,BroName,PagTitle)

you can just get your output with a single statement only

Code:

msgbox CheckLoadTime("Maps","Google Maps","Google Maps")

I just tried with your code and it works fine with a single statement. let me know if there is any issue
Suggestion: use Services.StartTransaction and Services.EndTransaction to get the page load time
see if this helps you.
