Python beginner here. I know what I want to do, but I don't know what all the parts of code are called, so I'm hoping someone can bear with me and help.I'm working on a script to add layers to a blank mxd, set the symbology of each layer, and convert the mxd to version 9.3 (per project requirements). The geodatabase has to stay in 9.3 also.A script is already in place that creates the blank mxd (copies a template), a blank geodatabase with 5 polylines, and a couple other shapefiles in the main model folder. I've gotten a script to work using arcpy that pulls in the all those things into the map in the correct order. I've created a template model with all the symbology I want, and have created .lyr files of everything. What I need to do now is get that symbology applied to the folder that I'm inputting (which is Test_Cr right now), save the mxd in version 9.3, and make sure the geodatabase stays in 9.3. If the map I'm starting with is v10_Test_Cr.mxd, the one that will be used is Test_Cr.mxd and v10 will get deleted.I must be missing something, because I'm not getting an error but the symbology is not changed in either Test_Cr or v10_Test_Cr after the script is run. I know I also have a lot of extra lines of junk, mostly because I don't know what everything does and I'm copying from various places .---
