Detailed Description and SymptomsInvestigationWe determined that this error happens when defining both recipients on the same line-
: READ &RECIPIENTS# ,,
:ADD_ATT RECIPIENT, '&RECIPIENTS#'
SolutionInstead of putting the whole recipient string onto one line from the read buffer, use a separate ADD_ATT command for each recipient in the Process tab.
: READ &RECIPIENTS# ,,
//start while loop and split the RECIPIENTS up
: ADD_ATT RECIPIENT, '&CUR_RECIPIENT#'
//end while loop
