Lesson 2.6 - Resolving Ambiguities in Variable Names

Description

It is possible for several variables with the same name to be included in your scripts. For example, you may write a script which contains a statement setting the value of the variable x. A user running your script might then submit a different value for x in a form. To distinguish between different variables of the same name, you can use the following prefixes with your variable names. If two or more of the above exist and you use #VariableName# with no prefix, it will return the value of the variable appearing higher in the following chart.
