Calculator error on arithmetic operation on the reading of digital bus

I have a digital bus as an output of verilog block.
Then putting these expressions on calculator gives me error.
value(VT("/COUNTER4V_A<31:0>") 1u ) / 9997
EDIT : numConv(value(VT("/COUNTER4V_A<31:0>") 1u ) "dec" t) / 9997

I would like to know as well how to plot it in decimal by default.
The way I do it right now is I need to RMB --> Digital Bus Properties --> Radix.
