F4 for custom field on UI not working correctly
I have just started with CRM web UI .
as to do practise I have added a custom field into standard view for sales lead, now I want to add F4 help for this field.
I searched over SDN for help and found following wiki, I followed required steps .
By following above wiki F4 Icon is appearing on view and by clicking that I am getting values from DOMAIN also.
But problem is after selecting any value it is not coming to input field.
i.e. if I selected 100 form F4 help popup , this will not come into input field and field will be BLANK.
Please guide me.
