Adding Point to Feature Class that has been created using Lat/Long and XY tool

I am trying to create a custom tool to take user input about point locations and add them into an existing feature class that already contains points that have been located using their Lat/Long values. I set up multiple arcpy.getparameterastext() such as name, size, etc. Latitude and Longitude are also point values, however when I enter everything in and run the tool I get this error...TypeError: expect single [X,Y[,Z[,M]]]

I assume it has something to do with setting up the XY coordinates but I am not sure how to fix this. It is probably something simple I am just not finding. Does anyone know how to fix this?
