Hi
Sorry I am very very new to infopath, I'm trying to pull out truncated accountID for the contact selector and your code works
xdMath:Eval(xdMath:Eval(../my:Requestor/my:Person, 'concat(my:AccountId, ";")'), "..")
but the domain names are still there, I have tried to follow Alex's walkthrough with no joy! it doesn't like something.
