Multiselect field doesn't work

[Samsul]

I am trying to create a doctype there is a multi-select type field… This field selects multiple items… But when I try to save the document… This field value can’t be saved…
Please give me suggestions about this.

Thanks,
Samsul

set mandatory to the link in child table.

Hi @Samsul @ganureddy :

Actually, need to set “In List View” property, on your link field in your child table.
Mandatory works too because “In List View” is marked on automatically, but are independent properties.
