Is it possible to use variables to define Xdialog parameters in Bash script?

I want to use variables to define the <max> and <def> parameters in an Xdialog spinbox. The code I am trying is:

Code:

Xdialog --2spinsbox 'Change the horizontal (x) and vertical (y) start point for your cropbox:' 0 60 \
1 $owcur $xcur 'x' \
1 $ohcur $ycur 'y' 2> $temppath/xytemp.tmp

The 1 $owcur $xcur 'x' should define the <min>, <max>, <def>, <label> parameters for the first item in the spinbox, but I am getting an error:
bad range parameters. Is it impossible to use variables in this way with Xdialog, or am I overlooking something stupid?

You didn't say what possible values the variables might have, so I had to experiment a a bit (I had no idea what a --2spinsbox was until I tried it out). Your command works just fine for me as long as I ensure that $xcur is smaller than $owcur, because the def needs to fall within the min-max range. Anything outside of that throws the error you're getting.

Thanks! I just figured this out myself a few minutes ago - it was a bad line in an awk script that was creating the variables.
