# Python in Field Calculator

I'm using the python example named on http://resources.arcgis.com/en/help/main/10.1/index.html#/Calculate_Field_examples/005s0000002m000000/

```Parser:
Python

Expression:
Reclass(!WELL_YIELD!)

Code Block:
def Reclass(WellYield):
if (WellYield >= 0 and WellYield <= 10):
return 1
elif (WellYield > 10 and WellYield <= 20):
return 2
elif (WellYield > 20 and WellYield <= 30):
return 3
elif (WellYield > 30):
return 4```

But i want to use this with 4 categories. So a wellyield with value 8 and category 1 gets a 1 return but a wellyield with value 8 and category 2 gets a 5 return and so on...

For example:
```def Reclass(WellYield):
if (Category = 1 and WellYield >= 0 and WellYield <= 720):
return 10
elif (Category = 1 and WellYield > 721 and WellYield <= 1085):
return 20
elif (Category = 1 and WellYield > 1086 and WellYield <= 1450):
return 30
elif (Category = 1 and  WellYield > 1451):
return 40

if (Category = 2 and WellYield >= 0 and WellYield <= 720):
return 20
elif (Category = 2 and WellYield > 721 and WellYield <= 1085):
return 30
elif (Category = 2 and WellYield > 1086 and WellYield <= 1450):
return 40
elif (Category = 2 and WellYield > 1451):
return 50

if (Category = 3 and WellYield >= 0 and WellYield <= 720):
return 30
elif (Category = 3 and WellYield > 721 and WellYield <= 1085):
return 40
elif (Category = 3 and WellYield > 1086 and WellYield <= 1450):
return 50
elif (Category = 3 and WellYield > 1451):
return 60

if (Category = 4 and  WellYield >= 0 and WellYield <= 720):
return 40
elif (Category = 4 and  WellYield > 721 and WellYield <= 1085):
return 50
elif (Category = 4 and  WellYield > 1086 and WellYield <= 1450):
return 60
elif (Category = 4 and  WellYield > 1451):
return 70
```

But of course this one doesnt work. How do i get it to work ?
