tep_db_prepare_input function

[mazter]

I'm working on orders. php file, at one point, I'm trying to output an input field with tep_db_prepare_input however it's not putting the values.

 

The line I'm having problem with is this line. I'm checking the values, by echo ing before input_field, it shows the values but when I give this variable to tep_draw_input_field, it's not showing anything.

 

<? echo tep_draw_input_field('refund_date', tep_date_short($order->info['refund_date'])); ?>

 

Any suggestion?

 

Thanks in advance
