How to open one script with another

This might be fairly easy to answer. I have two scripts (i.e. ScriptA.app and ScriptB.app). My goal is to open ScriptB.app from ScriptA.app. I have tried this:

--ScriptA.app
tell application "开发者_运维知识库ScriptB.app" to activate

But all I got was a window asking me Where is ScriptB.app? I scrolled through the list of applications but could not find ScriptB.app or ScriptA.app for that matter. I thought that was odd, as I saved both scripts as Applications. Any ideas on what I could be doing wrong?

When I tried this, saving both apps in the Applications folder, it worked fine.

Also it still works if I move either A or B or both to the desktop.
