What null values?

If empty, XThreads will use the blank value in that variable, if you've set one.

yes I have set the blank value, and I am using that blank value elsewhere....

BUT i need to check if the initial field is empty or not

eg. User Avatar, if not filled, then use default, BUT in another location, i need to check for the user Avatar, if present then display it and if NOT to display NOTHING, no default avatar either

Try

Code:

<if $GLOBALS['threadfields_x']['key']['num_values']!=0 then>
