Hey guys, not sure if this is the correct spot for my post. I keep finding myself with the urge to create a custom theme for my setup, even if it's solely just for my setup. Graphics design and designing with a wysiwyg format, like my olden days of Flash, and Dreamweaver I would be fine. Designing with code,...well, I totally blow. So I watch Mr. Carr's videos, then do the attempt, get frustrated, and do something else in life for a month, or so and then find myself once again on YouTube, for another cycle. When I watch the videos, I feel I'm doing what's being shown, making a copy of the theme folder, placing it in another location to work on, etc. More often than not, I seem to get shutdown as soon as I try to open one of the views. The most common error I get is an 'Invalid Markup' error, like VS finds a term it can't relate to, or find a proper reference for. So in-turn, I never get a chance to get a Designer window to open. I attached a screenshot, and I have no doubt it's user error, but if someone more fluent on the coding side could maybe give me a pointer on what I might do to resolve this, whether a setting change, or package I need to download, I would be greatly appreciative.
