How to send Gender on payment module?

[makeholer]

Hi guys,

 

I'm using one payment module that ask "gender" for the costumer, how can i send it on the payment form? im trying like this:

 

<input type="hidden" name="sexo" id="sexo" value="<?= $showOrder['customers_gender']; ?>" />

 

But it dont work, i dunno the right code to change on "customers_gender".

 

obs: when i change <?= $showOrder['customers_telephone']; ?> to simply "f" it send it right (female).

 

Thanks for any help,
