Create Multiple Rasters based on fields within a polygon that represent model results

I'm still new to Python and have written the following python script based on the ArcGIS 10.2 help. I'm sure I'm missing some thing simple, but can't figure out why the script doesn't run, no errors are being returned. Any help will be appreciated.

I'm tyring to join a feature class to multiple tables found within the same file geodatabase one at a time using the field called "Quins" then converting the joined feature class to a raster based on the list of fields given, which represent different model results. The output is a raster based on the input table name and the field name within the list. The field names are identical in all the tables within the tables. The difference in the tables are return periods of my six models that I need to generate rasters from.
