Are you enclosing the values for the textbox in quotes.
value='<%= variableName%>' or value="<%= variableName%>"
because when you put
with no quotes the space is treated as the end of the value and the browser thinks the next part, Block, is an attribute of some kind.
If this is not the case, can you confirm that the full value is stored in the Database.
Failing that please provide some more code examples.
They say, best men are moulded out of faults,
And, for the most, become much more the better
For being a little bad.
