I am having trouble creating a custom popup in ArcGIS Portal. What I want is a hyperlink to an external page that is filled with data from the clicked feature. The hyperlink looks like this: "http://www.co.richland.nd.us/RCIMS/Parcel.html?parcel=13-0000-02582.001" where the bold red part would come from the following data field: {RICHLAND.DBO.RC_Parcels.PIN_TXT}.
Thanks for any advice you may have. I tried to construct in the HTML mode, but couldn't get it to insert the data correctly into the HTML string.
