Output in model builder with python script tool not working

[Deepa]

Hi,

I am trying to use the script tool i made in the model builder. I want to get the output name as given by the user. For that "Output raster" is defined as string and the direction is Input in the parameter settings for that.  But then i could not see the output in the model builder so i added the "out file" as the fifth parameter with data type as raster and direction as output and type as derived obtained from blank. It still did not work. I want the green output in the model builder to get the name i defined in the string, in this example: test2 should be in the green color instead of outfile and to use this output for the next steps in the model builder. How to do that? 

 Thank you!
