Hi Joe, I understood your issue now.
If you create a form and try creating two fields with the same name but different cases , you wont succeed across the ODS Versions. So a Form can not have two fields with the same name.
In your case your documents are being manipulated by some script.
Now if the script uses doc.replaceitemvalue("MassBland","New value"), the MassBland Item gets a new value. regardless of the case used for "MassBland")
but if your script uses appenditemvalue, the picture is different. As i wrote before , a document can contain multiple items by the same name even with the same case eg
doc.appendItemValue("MassBland","1") creates an item MassBland with value 1
doc.appendItemValue("MassBland","1") creates a new item MassBland with value 1
doc.appendItemValue("massBland","2") creates a third item massBland with value 2
As far as your Notes Form is concerned, it will use the first massbland item regardless of the case
for access via a script , you need some work around which your script is using
See the difference between appenditemvalue and replaceitemvalue below (from domino designer help)
so in effect a form cannot have two fields with same name regardless of the case. however, a document may have multiple items by the same name. You can even have MASSBLAND item 10 times in a form with full uppercase with different values.
Note: In general, ReplaceItemValue is favored over AppendItemValue. If an item of the same name already exists in a document, AppendItemValue creates a second item of the same name, and the duplicate items are not accessible except through a work-around. If you are creating a new document, AppendItemValue is safe.
