When perlQ places the survey inside of your template, it embeds the survey within a table. The Survey Width parameter allows you to control the width of that table in which the survey appears.

In some cases, the text or style of some of your questions or answers may cause the survey table to be expanded outside of your defined Survey Width. Therefore, this field is more useful for specifying a width when the table is smaller than you would like it to appear, and wish to expand it.
