This command can be used to provide help text for the XpressDox interview:
<<Help(Interest,Enter the rate of interest, excluding the % sign)>>

The Help command can appear anywhere in the template, not necessarily anywhere close to where the data element will be used. But keep in mind that XpressDox will construct the interview in the order in which it reads the data elements in your template.

An alternative way of supplying help text for the interview is to put the help text in the fillpoint for the data element, following a ? symbol which follows the normal fillpoint contents, for example:
<<FormatNumber(Interest,'#0.00')?Enter the rate of interest>>

Help text can be included in any fillpoint in this way.
