Hi, i have a prompt where the user can select, for example:   Car Plane Title   The prompt is named "test"... and if i select all of them, than test1=Car, test2=Plane, test3=Title gets resolved right in the log.   Now i need to add them into one variable, so:   %let one = &test; %let two = test; %macro xyz; %if &test_count GT 0 %then %do i=2 %to &test_count; %let one = %sysfunc(catx(%quote(,), &one, &&&two.&i)); %end; ....   Result if i select for example "Plane" Plane   Result if i select 2 0,0   Result 3 0,0,0   Does anybody see where the mistake is? ...
