Ok so what i want is that i make a random number between 1 and 5 with my own function rand(1, 5) --- duh Then we have an array here: pawn Code: `new Names[] = {"Michael", "John", "Katey", "Richard", "Robbin"};` Then if it outputs 5 or any other number, select that string from the array. Like if rand(1, 5) outputs 2, then send the player a message with the name John in it. If it outputs 3, send the player a message with the name Katey in it. Can somebody explain me how? Thanks!

First this wont work pawn Code: `new Names[] = {"Michael", "John", "Katey", "Richard", "Robbin"};` because you create an array for arrays also you need two dimensions not one pawn Code: `new Names[][] ={ //just made the brace around the names to see better that they are arrays too    {"Michael"},    {"John"},    {"Katey"},    {"Richard"},    {"Robbin"}};` Than to your random problem pawn Code: `new string[128];format(string, sizeof(string), "%s says hello to you!", Names[random(sizeof(Names))]);SendClientMessage(playerid, 0xFFFFFFAA, string);//we get the array size with sizeof(Names) - the size of the first dimension is 5//so we do indirect random(5); which will return a number from -1 till 5 (0, 1, 2, 3 or 4)//so when random as example return 3 it will be Names[3] and that is "Richard"`

And that are for sure only two dimensions XD pawn Code: `new Names[][] ={    {'M', 'i', 'c', 'h', 'a', 'e', 'l'},    {'J', 'o', 'h', 'n'},    {'K', 'a', 't', 'e', 'y'},    {'R', 'i', 'c', 'h', 'a', 'r', 'd'},    {'R', 'o', 'b', 'b', 'i', 'n'}};`
