Field not found exception

please post the field your trying to call from the webservice. 9 times out of 10 the code is correct but the field is wrong! by wrong i mean:

If for example i have the field 'My ID' and i want to call it or query it, usually people search using 'My ID' which is the display version. Try using the internal name instead which if it does contain a space would be: 'My_x0020_ID'

also how long is the field? as there is also a strict ammount you can go upto which i think is a max of 32 characters. for a list of default internal names if your trying to reference them than refer to this list:

sorry to big to list here, within the list you can see the display name and the internal name... when referencing to the field use the internal or id if known.

also like to note without code we are only presuming here that the code is correct and you need to reference using internal not display name of a field ;)

Please go to list setting page and click on the field name. In the url check for query string "Field" the value after = sign is the name of column.
