Input string was not in a correct format

[Mark S]

I am installing a progam called Centennal Discovery for software and hardware inventory on our network. It has a web interface to view results with graphs and such. After installation, I try to access the web site but receive an error. I am not a programmer or web developer, but if you could help that would be great. Here is the information it provides.

Server Error in '/Discovery' Application.

Its from web request parsing process. please check the values entered in the web address are correct or not.

please post Global.Session_Start() function along with the address that you have typed.

Are there Dates used in the application?
It looks like you are supplying a date (or something) that is in a format that the application isn't expecting...

For example, American dates are formatted MM/DD/YYYY but Canadian dates are formatted as DD/MM/YYYY.
