Form is Not Able to Save Eventho field is not required

[zikrizainal]

Hi, why my form is not able to save eventho some fields are not required?

For instance, there is a date field with zero data.

I am unable to save this eventho its not required.

It says the entry is invalid.

But I dont care if theres data or not for the time being.

How to solve this?

Please show us how you have the Date column configured? 

Invalid is not the same as Required.  "Invalid" refers to the value in the field when Saving.  Do you have an Initial Value or Valid If expression implemented?
