yad/bash syntax of numeric field in form

[Joe]

I'm trying out my first form!

I have a very simple working script to print multiple copies of a print file and I'm trying to build a yad front end for it.

Everything works, but the initial value and range for COPIES is being ignored.

Eventually, I want to read variables from yad, but that is commented out until I get yad to work by itself.

What have I coded wrong so the range is ignored?

What (if anything) do I have to change or escape when I put the read code back in?
(I added a blank line after the commented out read just in case. It's only there while the line is commented out.)

Is there a way to tell "NUM" to return an integer? I know how to parse the float if I have to.

TIA

Your value for the NUM field is being passed to the file selection (FL) field.  You need an empty place holder after the FL field like this:

...

yad --title "${SCRIPT_NAME}" --on-top --form \

--field="Print File":FL '' \

--field="Copies:NUM" '2!0..50!1!' \

--field="One-sided":CHK \

--width=250

...

Thanks! That fixed it.

But, when I gave FL '', it filled the field with the name of the directory instead of (null). Then I saw that I needed ' ' to make it start with (null).

Just for anyone else reading this, I got it to start with a file in the directory by giving it the file name as the initial value. This had to include the path for this to work.
