I have a Nintex Workflow for Office 365 workflow with several task forms, many of which contain numeric controls that are used in calculations. For security purposes, I want to point these controls to variables rather than list columns.
However, when I try to point a control to a Number variable, the default value is 0, even though in the control settings, the default is blank. I want the field to show up empty so people don't have to remove all the 0's and replace them with valid numbers.
Any suggestions on how to make a number control default to blank without tying it to a list column?
