updating value from selectedvalue of DD is null

[Ben]

Hi,


With this code, when i click on Update button, the value updated of field
"wa" in the table is NULL.The update of the other field (not in a DD) works
good.
It seems that the selectedvalue of the dropdownlist (which exists, i tested
it with response.write) is not used as updating value.

Any idea why?
thanks
Ben
