This is my Custom Function and I want to edit it


Should the second parameter not be "list2" ?

Your example text is incorrect ( misplaced quote marks).
Should be:
CombineLists ( "1¶2¶3" ; "a¶b¶c" ; 2; "~" )
Note also there is another custom function listed here with the same name.

I find this easier to read:

Case (
startposition = ValueCount( list1 ) +1 ; "" ;
GetValue( list1; startposition) & separator &
GetValue( list2 ; startposition ) & ¶ &
CombineLists ( list1 ; list2 ; startposition+1; separator )
