Ok I have found a better solution to my issue.
How would I be able to get a random value from the array: users[loop] ?

Hi.
How would I be able to get a random value from the array: users[loop] ?
You cannot get a random number from an element of an array, you have to put a random number into an element of an array. I suspect I am not understanding what you need. Put this in a button:
Code: Select all
on mouseUp
repeat with y = 1 to 5
put random(999) into myArray[y]
end repeat
end mouseUp
Put a breakpoint at the last line. You will see five random numbers in the array. If you want a (random) one of these values, use Klaus' suggestion a post or two back. But is this what you meant?

Maybe something like
Code: Select all
put the keys of users into tKeys
put any line of tKeys into tChosenOne
put users[(tChosenOne)]
?????
Echoing Craig, but is this what you meant?

Perhaps I am unclear :/
Heres what I am looking to achieve:
- Enter all users, store it in users[loop]
- Get a random name from the array users[loop]
- Output the name that was randomly chosen

We still don't have any clue how you organize your array, means what is in what key!
We need to know before we finally can answer your question!
You are obviously NOT using any array form/format we have been discussed so far

SparkOut had the answer. Get a random key and output its value.
I don't really think you need an array for this though, a simple list would be enough unless you plan to add more data to the array later.

Appologies for not understanding. They are being stored like so:
Code: Select all
repeat with loop = 1 to 5
ask "Please enter the users name"
put it into name[loop]
end repeat
I would like to choose a random "user" from the "name[loop]" array.I am using the usernames later on in the program.

Hi smith8867,
1. do NOT use reserved (by Livecode) words as variable names!
NAME is e.g. a reserved word, you will get in trouble later on
2. We already gave you the answer to your last question, see SparkOuts last posting!
HInt: HIs ARRAY is named "users"
Best
