Som skal vedhæfte filen 1.pdf og det fungere egentlig fint nok, og den sender som den skal. Men når jeg forsøger at åbne filen så skriver den at den er beskadiget. Har fundet nogle tråde med det men synes ikke at kunne fange hvad der er gjort galt.


Nogen som kan fortælle evt, rette hvis det er "bare" lide?
