She is the best graphic designer I have ever seen.
Fast response in Skype, actually she is always there and response just in a sec.
She really cares about how you feel and she got the sense about design.
She changed the design very quick but also keep the high quality to meet my requirement. 
Overall, if everyone wants a high quality, fast delivery, low price, good communication, responsible, nekomimi and elf ears graphic designer, she is the best choice.
Highly recommended

i am not exactly sure what are you trying to do. About strings 
 
setarray(.@type$[0], "Whatever", "Words", "Going ", "Here");  strings you use for words and letters, for items you want an array, but not a string
setarray(.@item[0], 501, 502, 503);  but for items, you can also use it's aegis name (constant)
setarray(.@item[0], Red_Potion, Orange_Potion, Yellow_Potion);   this would call the related id, so even tho using the names here, it is still considered variables.
 
To say it simple: strings = words, variables = numbers
 
about your script:
 
OnInit: setarray $@type1,501,502,503,504,505; setarray $@type2,506,507,508,509,511;  You store it as a global, temporary variable, which isn't needed at all here. Neither it is required to call it oninit, better call it when it is actually needed. I would do it when that part of the script is called.
 
}else ; this is... well.. remove it
set .@randType$, "$@type2"; this is your actual problem. Your setting a string to a variable, also it's not specified which value of the array should be called. I think you want people to get 1 item out of 1 of those 2 random groups? There is actually no need to store them in arrays, i thin F_Rand comes in hany here
 
prontera,50,50,3 script seller 50,{ .@i = rand(1) // sets .@i randomly to either 0 or 1 if (.@i) getitem(callfunc("F_Rand", Red_Potion, Orange_Potion, 503)); // if .@i has a value get 1 random item, you can use constants or ID's else getitem(callfunc("F_Rand", Green_Potion, Red_Herb, 508 )); // and these if .@i is 0 end; }  
This would pretty much do what you want. Note: Even i use constants here for item id's, these are still considered variables (id's)
 
Now back to your question regarding strings.
.@i$ = "This is a string";  or in an array
setarray(.@i$[0], "We", "are", "all", "strings");  in an array you can store several informations, strings or variables. 
 
note: in an array, the index starts at 0, not at 1, this means
.@i$[0] = We
.@i$[1] = are
.@i$[2] = all
.@i$[3] = strings
 
you can also return the whole array like
implode(.@i$, " "); //this retuns all entries of the array, so its "We are all strings" Pick a random string
.@i$[rand(3)] // because index starts at 0, and rand(3) means random 0, 1, 2, or 3   
Note: i use .@ as temporal npc variables, this means they got deleted again once the npc finished and you don't waste memory to perm save it
Note 2: .@i$ is just an example, you can use any name you want for your strings or variables
 
about name of items, you can use getitemname. This works either with the ID or with the constant
getitemname(501) or getitemname(Red_Potion), you can also youe it for your arrays
 
setarray(.@items[0], Red_Potion, Yellow Potion, Orange Potion); .@r = rand(2); // .@r is either 0, 1, or 2 getitem(.@items[.@r]), 1; // you get your item from the array mesf("Congratiulations, you got a %s", getitemname(.@r)); //it receives the name of the item mesf is how we use it if you want do it with huld, you put %s as a placeholder for strings, %d as placeholder for variables, then after the comma you call them. If you want to do it the old way, you do
 
mes("Congratulations, you got a "+getitemname(.@r)+"");   
same applies for arrays with variables, so if you really want to store them
 
setarray .@items[0], 501, 502, 503, 504, 505; // .@items[0] is 501 and .@items [4] is 505 getitem .@items[rand(4], 1; // random item 0, 1, 2, 3 or 4  .@items[rand(4)] // because index starts at 0, and rand(3) means random 0, 1, 2, or 3
