This is a great place for help with your layout, however, everyone is going to the big TCA train meet in York, PA this week so there might not be much traffic around here for a few days. They will all be back in a week or so.
I am not 100% certain, but I think that layout video was from forum member TMack who posts here on the forum. If it is, maybe he will see your post and reply or you could try contacting him or leave a comment on his youtube channel. It is a very nice layout. Looks interesting and like it would be fun.
If that does not work, many here use SCARM and are very good with it. I don't happen to be one of them, but maybe one of the experienced SCARM users will be along to offer you some assistance. A couple of forum members have posted some tutorials on SCARM, if they are still here, a search for SCARM or SCARM tutorial or something along those lines may turn up something that could be helpful.
Edit: Should have said 'most' everyone is going to York. There are a few of us (like me) that don't go. And I see Moonman has posted a SCARM file for you, I believe he is one of the more knowledgeable SCARM users also, and may be able to help you with questions.
