Rename Variables After Copying a Form
Copying a form is a fast way to duplicate existing formatting and layout on a form. All contents of the form are copied, including variable names. Identical variable names in different forms can cause unpredictable results.
After you copy a form, rename the variables in the new form. For example, if variable FN exists in one form, rename the copied variable, FN, to FN_2. This reduces the likelihood of a un-populated variable being used in a condition for the wrong form.
