Data Feeds and Vouchers personalization

Hey!  Yes I think you could enclose that all within an IF statement in Liquid.   i.e

// Getting the value of the code for the individual send
{% assign currentVouchCode = {% voucher ('MeFeedCode') %} %}

// Checking if there is a value
{% if currentVouchCode != blank %]
   {{ currentVouchCode }}
{% else %}
   Sorry there is no code listed
{% endif %}

Something like this should work - test it out.
