Impossible to combine fields and line break if empty fields

[NICK75]

I am trying to have a formula which give me the possibility to have on the same line two fields separated by a coma. This is tricky, because, i need also to have in the formula that if the field is empty if it not showing the empty space or make a break line.

Right now I have this, 

IF({MARQUES}, " " & {MARQUES} & "\n") &

IF({DESIGNER}, " , " & {DESIGNER} & "\n") &

IF({DATATION}, "  " & {DATATION} & "\n") &

IF({COLLECTION}, " " & {COLLECTION} & "\n") &

IF({FABRICATION}, " " & {FABRICATION} & "\n") &

IF({PRODUIT}, " " & {PRODUIT} & "\n") &

IF({MODELE}, " - " & {MODELE} & "\n") &

IF({MATIERES}, " " & {MATIERES} & "\n") &

IF({COULEURS}, " " & {COULEURS} & "\n") &

IF({DETAIL}, " " & {DETAIL}) &

IF({GRIFFES}, " , " & {GRIFFES} & "\n") &

IF({PROVENANCE}, " " & {PROVENANCE} & "\n") &

IF({TAILLES}, " " & {TAILLES} & "\n") &

IF({CONDITION REPORT}, " " & {CONDITION REPORT} & "\n") &

IF({ICONOGRAPHIES}, " " & {ICONOGRAPHIES}

and it is showing this for the moment

MARQUES

X DESIGNER

I would like to have MARQUES X DESIGNER

 If i do correction and  write 

IF({MARQUES}, " " & {MARQUES}) &

IF({DESIGNER}, " X " & {DESIGNER} & "\n") &

Then I will have 

MARQUES X DESIGNER

But If I do so, and if the field MARQUES is EMPTY it create a empty field with a ,

I will have 

, DESIGNER

To check two fields and branch conditionally, use the AND function.

How to use Like this.

IF(
  AND({MARQUES},{DESIGNER}),
  {MARQUES} & " X " & {DESIGNER} & "\n",
  IF({MARQUES}, " " & {MARQUES} & "\n") &
  IF({DESIGNER}, " " & {DESIGNER} & "\n")
)

I still have a problem i would like to use REGEX_REPLACE() to remove all white space next to a line break but I do know how to write it correctly.

here's what I have so far and where should insert and write with REGEX_REPLACE (?????)

IF(AND({MARQUES},{DESIGNER}),

{MARQUES} & " X " & {DESIGNER} & "\n",

IF({MARQUES}, " " & {MARQUES} & "\n") &

IF({DESIGNER}, " " & {DESIGNER} & "\n"))&

IF({FABRICATION}, " " & {FABRICATION} & "\n") &

IF(AND({DATATION},{COLLECTION}),

{DATATION} & " - " & {COLLECTION} & "\n",

IF({DATATION}, " " & {DATATION} & "\n") &

IF({COLLECTION}, " " & {COLLECTION} & "\n"))&

IF(AND({PRODUIT},{MODELE}),

{PRODUIT} & " - " & {MODELE} & "\n",

IF({PRODUIT}, " " & {PRODUIT} & "\n") &

IF({MODELE}, " " & {MODELE} & "\n"))&

IF({MATIERES}, " " & {MATIERES} & "\n") &

IF({COULEURS}, " " & {COULEURS} & "\n")&

IF({DETAIL}, " " & {DETAIL} & "\n")&

IF({GRIFFES}, " " & {GRIFFES} & "\n") &

IF({PROVENANCE}, " " & {PROVENANCE} & "\n") &

IF({TAILLES}, " " & {TAILLES} & "\n") &

IF({CONDITION REPORT}, " " & {CONDITION REPORT} & "\n") &

IF({ICONOGRAPHIES}, " " & {ICONOGRAPHIES} & "\n") &

IF({CITES}, " " & {CITES})
