The Viridian Gym page has two problems, although one might not be a "problem" per se.
The first thing I noticed, which is definitely a problem, is that the HG/SS trainer table has what appears to be a scripting error. The table is stretched out and you can see a part of the "coding" on the bottom of the table. The second issue is that when I tried to see if I could fix this error I realized their is no "Edit" option for this page. Is the page supposed to be uneditable by ordinary users or is that another error?
