Hi,
This issue was caused by an old snippet in the SPJS_vLookup_frontend.js file where all fields with an internal name starting with “_” would be initially hidden.
I’ll fix this in the next version, but until then you can fix it by adding this to your Custom JS:
spjs.vLookup.init_vLookupFields = function (){
spjs.vLookup.fields = {};
jQspjs.each(spjs.utility.data.fields,function(fin,tr){
spjs.vLookup.fields[fin] = {"tr":tr,"fin":fin,"disp":tr.FieldDispName,"type":tr.FieldType};
});
spjs.vLookup.init_vLookupID();
};
