Refer to other attributes value while creat block_does not work

[Anonymous]

Hi, experts:

My problem is while I am creating a block with 4 attributes I already defined the first 3 attributes and for the 4th attributes I want it to be the combination of the 3s that I already created so I insert 3 fields which are the values of the first three attributes (actually they are texts in block editor);

when I insert the created block into drawing and input values for the first 3 attributes, for the 4th attributes I does not get what I want, actually there is only --------, the "sync" command under the block tab or the "update field" command do not work;

so what is the problem, if the method I employed is wrong?

thanks a lot

Always post the block file.
