Python Script not working as Tool

[KellyZiegenfuss2]

Hi All,

I have a script that works in python, but when I create a tool for it, it no longer works. I have attached the code, does anybody know what could be wrong? I have also copy and pasted the error I received. Thanks!

What are the parameters for the tool?  a screen grab or documentation of the parameter, type, etc would be useful

[KellyZiegenfuss2]

The parameters two shapefiles and a specified field from each shapefile

The error indicates there is a problem with your inputs for the select layer by location. You need to generate a layer from the buffer in your script. The select layer by location will only take layer files not output features.

#buffer the dissolved Centerlines layer
arcpy.Buffer_analysis ("lyr_dissolved", "buffer", "50 Feet", "", "", "", "")

arcpy.MakeFeatureLayer_management("buffer", "lyr_buffer")

#Delete any centerlines that will not be used
arcpy.SelectLayerByLocation_management("lyr_buffer","INTERSECT","lyr_Segments","","NEW_SELECTION")
