R Flag Syntax Error

[MichaelSlevin]

I am trying to use the expression below to pull data on from a feature layer, I have used x to protect some data but otherwise the formula is exact:

pulldata("@layer", "getValue", "attributes.XXXX", 'https://services9.arcgis.com/P6kyywx46o75oKam/arcgis/rest/services/XXXX/FeatureServer/0',concat("ReferenceNumber ='",${ReferenceNumber},"'"))

The problem is, Connect is generating a form however, instead of a field into which information is populated, I am getting the below error:

SyntaxError: Invalid regular expression flag 'R' in expression: *repeats formula above*

Only problem is, I don't know what that error message means.

Any help?

Not sure on this one but I know that normally you cannot have a function inside a pulldata.  

Make a field that has the concat part then use that field in this call.
