[phpesp-general] missing values/radio buttons

[Christopher K. <ck...@im...>]

  Hi. I am running phpESP 1.3.x and have a
question/comment on how it handles missing values. I
collect a lot of Likert data using radio buttons and
was wondering why the scales are calibrated starting at
0 in the source code? When I look at the CSV export it means that I
have to shift everything, which is not that big a deal.
The problem is that when a person skips an answer it
looks like it is inserting a 0 in the field to indicate
a missing value. This leads to obvious problems when it
comes to analysis.  Many of the items are not required, so it is difficult 
to distinguish between a blank answer and someone who answered with the 
first radio button.

I'm sorry if I missed something obvious in the docs. I
think that this is a great project and just want to
suggest and edge that could be smoothed.

Cheers,

--chris
