I have a variable called $String which can contain 3 random numbers like so...


I then have $Num which is a single number from 1 - 20, I want to add $String 
and $Num together like this


So I would end up with $String1="12,94,423"; and then I can enter that value 
into my session....


I have tried everyway I can think of but it never works

The reason for doing this is so I can store multiple $Strings in the session 
and use them later for a search.

Can anyone help?
