Thanks, but I must not have explained myself well. I don't know what the algorithm is that converts the 'CompanyName' to 'Soundexe'. For example, CompanyName = 'Accenture', and Soundexe = 'ACCENTU'.

At first I thought it was simply a 'soundex' function - but it is not. I really don't think that anyone could crack this, but I am hopeful!!!
