Patrick,
I appreciate the offer. I would be happy to provide a testimonial of qRules or your training either way. Frankly, qRules has saved my sanity. The ability to write back to a data source is simply beyond my level of knowledge. qRules and this forum have opened the door to the point that I can now train myself to do just about anything. Perhaps the one thing that has made a difference is the ability to essentially take a client intake sheet that contains the baseline data needed for our business and turn it into one form. Prior to qRules, we did this in word or manually and then retyped. Now, we have one electronic form and inputting in the form also updates the database. It requires writting to more than a dozen lists.
With respect to your questions:
1) Let me know what product you specifically want me to talk about - and if you have a specific feature in mind I will be happy to emphasize that point. I feel comfortable talking about your customer support, this forum, SaveToSharePointList, and then the general use of qRules. I can also talk about how it has enhanced Sharepoint and made forms more functional for my small business. I will also be happy to talk about the fact that I am an end-user with limited skills - Lawyer, MBA, and Engineer, but never any experience programming.
2) I pull into my form the 'cases' list using REST to conduct a server-side query that only retrieves active class for a specific lawyer. Cases have an associated ClientID which represent a specific client in 'clients'. I do not have clients in my form as of yet becuase I need to convert the list of clientIDs into a REST query. ClientID is the ID field in the 'client' list.
4) I think my problem lies in understanding how to convert the results of one REST query into a new concatenanted REST query. I understand contatenate and the general REST query format, but the conversion from tabular to a string is beyond my knowledge. I know how to do this with excel, but not with Infopath.
