Found my mistake. I put the lines after form = SQLFORM(..) instead of before. However, this method still leaves a bad taste in my mouth. Since every request is also sending a table redifinition, this seems like un-needed overhead. This also has the problem of what if the given database does not allow the tables to be redefined, and only allows submissions. This is a future possibilty I want to account for. Am I correct that this solution would no longer work? Is there any other possile method to make the field of an sqlform be unchangable (at least visibly) and also be pre-filled?
