LongText in report dont't expand

As you probably know, long text fields can contain quite a lot of data and it wouldn't make sense to try and show it all.

Not sure how many characters your trying to print in the report but there is a limit of 64000

I also assume your setting Can Grow property to True already

Yes "Can Grow" settings is true and there is less than 64000 characters. Even if I expand the txt-box manualy to the hole page it is stripped the same place and after 200 characters. I have retyped the messages -  but same result ::).

and nothing in formatting in table field or on report which could limit it? Maybe look at query if report is based on one rather than table.

Hi Terry
Thanks for your comments. Finally I have figured out that I cant copy the field from one field to another. If I do this data is striped away - all above 256 characters.

sounds as though your long text is getting converted to short text ...
