Do you know what functionality you may lose if you remove a field from a screen? Please speak with your OpusXenta consultant prior to making any changes to discuss the possible consequences of the changes made.
Some fields have additional functionality that if removed may cause other aspects of byondpro functionality to fail.
There are a couple of approaches depending on whether you are confident that removal will have no impact or not.
For example, if you are unsure about removing the Baby Details field completely, you can find the field and simply type in the Create Script box Hidden=True; as shown in the screen prints below.
That way the field is supressed from the screen and on saving the person record, all functionality associated to that field would remain.
