0 Finding Lava Output Tags 1 Aaron Fuchs posted 6 Years Ago I am new to using Rock and have thus far been able to get by with all I need to do by just modifying the prebuilt mail merge documents to meet my needs. I need to print address labels with envelope numbers on them. I followed the guide on Shoulder the Boulder for creating envelope numbers - and all is good. I got the mailing label word doc and am not sure what I need to put to add the envelope number.In Home -> General Settings -> Person Attributes -> I have Envelope Number, it has an id of 2362, and a key of core_GivingEnvelopeNumber. I tried {{Row.core_GivingEnvelopeNumber}} but it did not work. What have I done wrong - and probably more importantly - where do I find all the tags? TY
