# How to add line to a table based on having a value entered in the previous line?

Asked by flandsberg on 2017-05-05

Hi,

I have a table in which each row is a number value from measuring the length of river segments in a plot. I would like to add a line in the table only if a value is entered in the previous line so that the card is not overcrowded. How can I do this?

Thanks!

Florence

Dear Florence, 
If you are talking about Collect Mobile and the table corresponds to a multiple entity in the survey designer with a Code attribute as key, then the answer is NO! We don't support such a feature nowadays, the rows for multiple entities are predefined.  
Many thanks,
