Percentages

[SLouq]

Why when I try to calculate a Percentage of a polygon, the answer comes back null?

Could this be bc of the data type of my Percent column? 

It is set to Float

[DanPatterson · Accepted solution]

python parser, and try dropping the commas in the number

float should be ok, but double may be the one to use

That worked!
