Export to csv in Connectivity6

I'm trying to export a table (where i have data from a chronoform) to csv but a i can't.
i've done a read data function ("read_regs"), it Works ok beacuse i've used it with a table view and everything was right. But when i used with the csv function i have problems
In the csv i put {var:rear_regs} in the data provider and when i execute the function the file has this information:
regs
Array
Array
Array
..
if i put {var:rear_regs.0} or {var:rear_regs.1}.. i get the information for each register but i need all the info in one csv.
I'm sure its a silly thing i cant see, can anyone help me please?

Thank You!

Hello Max
Sorry to crash in this post... It helped me so thank you for the one posting this question and for your answer.

I was wondering what is the reason for having [n] in the data provider field?

Thank you

Hi Amelia,

To get the correct structure of data required by the "csv" action, the read data returns a complex structure, but the csv expects a numerically indexed array of data sets.
