I am using the enter processing times based on patient's location/area option in FlexSim Healthcare 5.0.12 ("process" ->"processing time" drop-down list -> "based on patient's location/area"). It seems like if users select the processing time from the drop-down list (e.g. "use an expression" -> "choose a distribution") or enter a time in the "Then the processing time is" fields, the default expression does not work, and the string array in the code does not read the expression as it supposed to. Users have to always manually add quotation marks to the default expression or the entered processing time to solve the problem. Hope the next version of FlexSim could fix this. Thanks!
