I have a system script i am calling from a Template. i have a parameter in the Tempalate that contains some path information the script needs. this will be set differently everytime the template is used. I can not figure out how to pass the parameter value in the runScript call? if i just hard code it as a string it works fine. But as soon as i use the parameter, even though it has the same value as the string, i get a syntax error. Thanks for any help. ---

What is the datatype of the parameter that you are passing to the script? It it coming from a UDT? ---

No, not from a UDT ( I dont think). it is just a string value entered in a custom property parameter. All i am doing is trying to determine is different sub systems have active alarms by using the system.alert.queryAlertStatus(). Here is the Module Defiition: def SystemActiveAlerts(System,UnAck, Ack ): import system return system.alert.queryAlertStatus(path=System, activeAndUnacked=UnAck, activeAndAcked=Ack).rowCount Here is my call, which works, where ‘CA3/PCW/_’ is a path filter: runScript("app.alert.SystemActiveAlerts('CA3/PCW/_’, 1, 1)", 5000) Here is the call that does not work substituting the string above with the same string in a custom property, where Status.System containes CA3/PCW/\*: runScript(“app.alert.SystemActiveAlerts({Status.System}, 1, 1)”, 5000) This results in a Syntax error.

I think your call is literally passing in the text “{Status.System}” as the first parameter. Does this work for you? ```auto runScript("app.alert.SystemActiveAlerts(" + toStr({Status.System}) + ", 1, 1)", 5000) ``` Dan ---

no luck. with it in quotes like that seems like it is literally sending + toStr({Status.System}) +, tried without the quotes and the + and still no joy. Thanks, ---

In what scope is this expression being run from, an expression tag? Property binding? Also, what component is the custom property part of? A root container, or a component within the container? ---

Not sure i fully understand the question, but will try. This is on a template. I have an internal Property defined as an integer called “Acitve” I have a Template Parameter defined as a String called “System” Active is linked to an Expresion, the expresion equals: runScript(“app.alert.SystemActiveAlerts({Status.System}, 1, 1)”, 5000) System has a string entered into it of: CA3/PCW/\* Have also tried: ‘CA3/PCW/\*’ both result in a syntax error. If i replace {Status.System}, wtih ‘CA3/PCW/\*’ in the expresion, the expresion then works. Thanks, ---

Oops forgot, both parameters (System and Active) are defined on the root container. ---

Ok, thanks for clearing that up, I think I was getting something confused. Try using concat(): `runScript(concat("app.alert.SystemActiveAlerts('",{Status.System},"', 1, 1)"),5000) ` The single quotes around your string that your sending to SystemActiveAlerts should fix the syntax error, if not, can you post the full syntax error? Thanks. ---

That did it! 😃 Now all i have to do, is read up on Concat so I can figure out why. Thanks for the help. ---

Using the concatentation opeators (+) should’ve worked too, it sounds like those single quotes were the missing piece. Glad you got it working.
