You have a sub-report that works pulling back data. You change it to display
multiple columns either horizontal or vertical and the data disappears on the screen.
Once you choose
Format with Multiple Columns a new tab called
Layout will appear on the
Section Expert for the
Details section. Click on the
Layout tab and make sure that the width is greater than 0. For some reason, mine always defaults to 0 with Crystal Reports 2011 (v14). You'll want to set the value to be high enough to display the data you want to display.
