The problem is that it doesn't see the value at all
trueVal = form.getlist(storeColNames[i])
test = ','.join(trueVal)
if len(test) == 0:
trueVal == ''
It simply doesn't register storeColNames[i] if there is nothing provided
from the referring page. Here's a test printout:
SKU ['prodSKU1']
Category ['prodCat1']
Name ['name1']
Title ['title1']
Description ['descr']
Price ['123.45']
SortFactor ['500']
Availability ['1']
OutOfStock ['0']
ShipFlatFee ['10']
ShipPercentPrice ['5']
ShipPercentWeight ['2']
TempPrice ['1']
LastDatePrice ['2000-01-01']
Weight ['2.5']
Metal ['14k gold']
PercentMetal ['25']
insert into products (SKU, Category, Name, Title, Description, Price,
SortFactor, Availability, OutOfStock, ShipFlatFee, ShipPercentPrice,
ShipPercentWeight, Associations, TempPrice, LastDatePrice, Weight, Metal,
PercentMetal) values("prodSKU1", "prodCat1", "name1", "title1", "descr",
"123.45", "500", "1", "0", "10", "5", "2", "1", "2000-01-01", "2.5", "14k
gold", "25"); Insert/update successful!

You can see from the above part with breaks that "Availability" isn't
logged. But it is in the insert statement...without a value, which throws an
error. The complete code follows:
