Hi, I cannot install the High Sierra combo until I install High Sierra. When I go to the App Store, I get the following error message:
This copy of the Install macOS High Sierra.app application is damaged and can't be used to install macOS.
Please help.

It's just that you already have an older copy of the Installer in Applications Folder called Install MacOS High Sierras, you can run that one & have it work if you disconnect from the Internet & sety the Date.Time back to 2014.
Or you can delete it & download a new copy.
Hi,
I deleted and re-downloaded, but I get an error message saying that I need to have 10.13 before I install the combo, 10.13.6. Where do I get 10.13?
You've already downloaded it. Look in Downloads and Applications folders and delete the installer. Then re-download it.
This is 10.13.6. I need 10.13.
No, it is the full High Sierra installer. There is no 10.13.0, all installers have been upgraded to 10.13.6.
The message should really say "You need 10.13 or greater", or "You need 10.13 at the very least". :)
