I am keeping the parameters in a excel file required for shell script and read them using Excel VBO and concatenating them like this "sh myshell.sh" + "par1" + "par2" and forming a string "sh myshell.sh par1 par2" and its working fine when the excel will have only one set of parameters problem comes when the excel have multiple parameters records its concatenating the previous values  of parameter and current values of parameters also like this sh myshell.sh par1 par 2 par3 par4 how can i avoid this situation in the second run i should get the string like sh myshell.sh par3 par4 only without previous values.I am attaching my blueprism flow in the attachment. Thanks in advance please help in solving this issue.   Thanks, Rahul.
