Thanks,
Works out great! Now if we could get that as a native option in a resource with percent bar/graphics then it would totally rock! 
Also, something that has been discussed extensively in previous discussions: the ability to group the Nodes in the Top XX resource by Custom Property.
We have close to 2000 nodes that we svan and there is no way to tell which country or region (Custom Property) has the least/most free ports available.
Just wanted to point that out once again.
Thanks for the rapid feedback and custom report!
