I have created the task variable which is pointing to Global Variable (i.e.. CONFIGURABLE(Prefix)) and I am trying to retrieve this task variable and still not successful (my goal is to set some value to these Global Variables using $workflow->SetVariable("Prefix", "****"); in my first task) and then use this variable in different other task to do SCRIPT based decisions to do the next tasks [ie..if ("$IW_CV(Prefix)" != null) {true;}else{false;}].ThanksArchie
