Hi,<br/><br/>Which is correct?<br/><br/>AT this stage, we connect a to b.<br/><br/>IN this stage, we connect a to b.<br/><br/>AT this step, we connect a to b.<br/><br/>IN this step, we connect a to b.<br/><br/>Is there a reason why people seem to use both AT and IN? Or is there something I am not seeing here?<br/><br/>Thank you.
