Hi Tina Katic, actually yeah, I have seen this before - in our initial configuration, we had a "lead notes" field that was configured as a normal text field and it cut off at 100 characters. We had to switch to using a real large text field, which is a pain but you can do it.
The field needs to be large text, not just on the form but in the actual database. That means you will have to create a new contact field, and transfer the data from your existing comments field into the new field.
- Go to Setup->fields and views
- create a new contact field of type "large text"
- Export all of your contacts to a CSV file (you can do that by making a segment where the only condition is that the email address contain "@" and then export it). Make sure you're exporting the comments field.
- Import the CSV file, but map the old comments field to the new comments field.
- Change all of your form processing steps to write the comments data to the new comments field. This is the time-consuming step, if you have a lot of forms.
Best to fix this now, the longer you go the harder it will be and the more data you'll lose.
