For a start, try using single quotes around your literals ...

You may first want to create an sp to help. Something like:
Create procedure [dbo].[s_ExecutePackage]
@FilePath varchar(1000) ,
@Filename varchar(128)
as
Declare @cmd varchar(1000)
select @cmd = 'dtexec /F "' + @FilePath + @Filename + '"'
exec master..xp_cmdshell @cmd
go
This will help you execute the package from within your sp, once you have enabled use of xp_cmdshell, of course.
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
