Can anyone figure out what simple error I am making? The following code ...
tlb=widget_base(title='Test', /column)
dims=['64','128','256','512','768','1024']
xbase=widget_base(tlb, /row)
xdim_id=cw_bgroup(xbase, dims, /exclusive, font='arial*14', $
/no_release, /return_index, /row, uvalue='xdim')
ybase=widget_base(tlb, /row)
ydim_id=cw_bgroup(ybase, dims, /label_left, /exclusive, font='arial*14', $
/no_release, /return_index, /row, uvalue='ydim')
widget_control, tlb, /realize
produces this error during execution...
% WIDGET_LABEL: String expression required in this context: LABEL_LEFT.
i.e. it does not seem to like the keyword LABEL_LEFT. I get the same error
with LABEL_TOP.
I am running Windows v5.2 under Win95.
Thanks for any feedback.

thanks for pointing out my misunderstanding. I was thinking that
"LABEL_TOP" would cause the individual button labels within the group to be
placed above the radio buttons, but I see that it is referring to the
lead-in question/label for the group. will edit cw_bgroup itself.

You have to set LABEL_LEFT to the string value you want the label to be.
Similar for LABEL_TOP. Try
LABEL_TOP='Top label',LABEL_LEFT='must be left label'
