Hello Scooby Gang

What I've got is an InfoPath form which has a drop down choice of applications for approval. I'm using repeating tales for users who need to pick more than one application to get approved.

I'm using the exporting method as detailed here: https://dataqueen.unlimitedviz.com/2013/05/exporting-infopath-repeating-table-data-with-nintex-workflow/ the workflow was working fine without the SQL steps, but now I'm getting an error:

Error performing database operation. Format of the initialization string does not conform to specification starting at index 0.

Any ideas to correct or a simpler method to achieve the same end?
