Welcome to the Rainmeter forum Anna!
You would want to look at assigning a
Group to the skins you want to unload.
Add
Group=[i]YourGroupName[/i] to the [Rainmeter] section of those skins.
Then look at the
Group Bangs to DeActivate the group. Or use
Hide/Show Groups...
In the [Rainmeter] section of your main skin have
OnRefresh=!DeActivateGroup [i]YourGroupName[/i]
Note this will DeActivate all of those skins in
YourGroupName on the initial load, so you should load this skin before any of the other skins in the group if you want them to be active.
You mentioned the main skin will refresh from an update, so you may want to add the !DeActivateGroup bang to that update rather than to the main skin refresh I described above;
OnUpdateAction=!DeActivateGroup [i]YourGroupName[/i]
There are a number of ways to achieve your purpose, but without seeing your code, you will have to determine which way works best for you.
