How to save script task input into multiple cdts?

Question

I am uploading multiple forms with a file on the interface and I need to save the document name with extension. When I tried getting the file name on the interface, it was giving me error because it cant accept lists in document function. 
 So after filling out the form, I created a script task to get file name and extension by using forEach function into two inputs. 
 Now the problem is how to save it. 
 I put ac!fileName_text & "." & ac!fileExtension_text and save into ri!cdt.fileName_text. 
 But it was only writing to the first cdt in a weird format like fileName_text (1st upload) ; fileName_text.fileExtension_text ( 2nd upload) ; fileExtention_text ( 1st upload). 
 
 Please let me know how can I fix it. 
 Thanks

Not sure i have all relevant details, but you could try just doing this in a single output: a!forEach(
 pv!documentList,
 {
 fileName_text: document(fv!item, "name"),
 fileExtension_text: document(fv!item, "extension")
 }
) 
 You can probably just save this into your CDT array PV and have that work -- I assume you have a CDT array PV with those properties in place.
