I want to create a detail attribute in VEX that randomly selects numbers between 1 and 5 and I want to use the iteration number in a for-each loop as the seed to shuffle between the numbers 1 to 5. Been having some trouble all morning trying to figure it out. Hope you can help.

Hello,

A possible way may be using "sample_discrete" [www.sidefx.com] VEX function.

Try this in a detail wrangle, with foreach_countconnected to second input:
int iter = detail(1, "iteration");
i@num_rnd = int(rand(iter) * 5) + 1;

Example output for 100 iterations:
3152111453115511555142124542515455352525224235514222554453113115132144314525544324311322441345342534

@eriksky beat me to it, though with a different function.

Awesome thank you!!!! Works great!

int iter = chi("iteration");
i@num_rnd = int(rand(iter) * 4) + 2;

What I ended up doing.
