Using the random() in LiveCode

I have an issue with using

the random defined function in livecode.

Here is a code snippet:

// 97 -> 122 = lower case...
put random(97,122) into randASCII

The program is to create an order number, the order number consists of the first character of the first name, first character of last name, random number between 1 and 9, and a random ASCII value between 97 and 122 (the lower case characters.)

Thank you very much!
