Neil,

My favorite way to deal with this is to just always add one and then remove the one bad one, no messy IFs involved:

lcConcatenatedString = ""
for i = 1 to n
   lcConcatenatedString = lcConcatenatedString + "," + transform( i )
endfor

lcConcatenatedString = substr( lcConcatenatedString, 2 ) && pull off the initial ,

>Im getting confused on putting the commas in and how to stop putting a comma in if it is the last email address found. Can anybody help me please?
