so, this is my ultrasimple script that outputs various numbers of notes, depending on user input. of course, if someone put 14 or more in input field i got the following error:
Warning: array_rand() [function.array-rand]: Second argument has to be between 1 and the number of elements in the array.....
so the question is: what to change so users can input for example number 999 and the script would output 999 random notes from array?
thank you in advance
and...
