Convert user inputs to string

Hello world !
I’m using a dropdown data ui from the data sahpes package to promt the user to select the duct type . After that i want to get the index of the user inputs from the duct types list which ia already extracted . i get the -1 index i checked the user inputs on the multinpuplatform ++ it apears that it gives the user input as a list ! I cant convert that list to a single line string to get the index of the user inputs ! am I doing something wrong ?
Revit version
Dynamo Version 1.3.4

replace the node IndexOf by node All Indices Of
