How is one text value more or less than another text value?
What have you tried, where are you stuck?

Text box or number entry?
What is the trigger for comparison - when a button is pressed? as user types?
What is the logic for comparison?
is ABC?abc?
is 00 \< 1?
is a string with greater length considered "more"

if you only want numbers you would be better using the numerical entry. Otherwise you will also have to filter out any non-numerical values. or have you already done that part?

that is a much better explanation and since its with an amost complete flow, much easier to assist you.

Take a look at the flow that @Steve-Mcl gave you.
Compare it to what you have said that you want.
You should be able to get it to work on your own...

actually the flow as written by @Steve-Mcl sortof works. The problem is that while the flow.B changes, the value displayed on the dashbord does not change.
However if you add a very small delay between the function node and the B `ui_text_input` node, the value will show on the dashboard.
I would aslo suggest changing the `delay time` in the `ui_text_input` node to 0.
