Treat blank cells as 0 for conditions #25

Closed damonkellis closed 8 years ago

damonkellis commented 8 years ago

What is current behaviour with empty student data fields? I suspect that they are not treated as 0 for the purpose of conditions (so, for example, a conditional like "<2" will not identify those students with a blank in that field).

can confirm that imported data sets that have blank cells are not treated as "0" this needs to be changed so that filtering of data can occur within SRES. Is there a way to programmatically treat these empty cells as zero? This fix would save quite a bit of data wrangling time.

An alternative (used in SRESv1) is to add 'is empty' and 'is not empty' conditions - that way, users can still enter a zero (e.g. zeor marks) and not have this be the same as an empty (i.e. never-entered).
