Table contains value?

[StealthFD]

Having an issue trying to figure out how to see if a value exisits in a table.

I am randomizing a test/quiz app and I'm pretty sure I'm on the right track here -
#1. create a temp table to store the used question numbers in
#2. generate a random number
#3a. IF that number is not in the table, THEN do some stuff and write that question number into the temp table - OR
#3b if that number is in the table GOTO #2

I just can't seem to figure out how to check to see if a table contains a value... or how to "GOTO #2"

random_question = Math.Random(10);
if (table.used_q does not contain random_question) then
	Paragraph.SetText("a_box", Question_Bank[random_question].A);
             Paragraph.SetText("q_box", Question_Bank[random_question].Q);
             table_row = table_row + 1;
             Table.Insert(used_q, table_row, random_question);
else
	loop back to random_question generation
end

Can someone point me to an example please?

Thanks guys!

StealthFD,

I built a quiz engine that would randomize a test and the answers. (1) In short what I did was have a temporary master table that contained all the questions and answers. (2) I would then use a for loop to build a table with the number of question I want to ask and to generate a random number that will be the index for the question pulled from the temporary master table. That question was then placed in the test to be given table as the next question in line.

Thanks Tigger... I was thinking along that line once too. But how did you avoid repeating questions?

oh yeah, I forgot to put put that in there. After extracting the random question from the temporary master table I would delete that index.
