Hello All,
First of all I want to thank everyone in here for the amazing job you guys are doing! And especially Sambapos creators 
I’m configuring this soft to use it in a takeaway shop in London, UK. And would love to integrate the postcode search feature. I found a guide for V3 - http://www.sambapos.org/en/content/how-integrate-sambapos-post-code-databases
but I couldn’t get it to work with V4, it basically shows “Postcode=£1; Street=£2; ity=£2 :postcodes.txt” instead of an empty field to type in the postcode.
and this is what I have in the custom field’s editing format - “Postcode=$1; Street=$2; City=$2 C:\postcodes.txt”
thanks in advance
