Here you can define you user variables.

Set

variable: Creates a normal user variable. This will always be lower case and spaces are not allowed.

static: This is a static that can not be populated dynamically in workflows.

as

string: Sets the variable/static as a text string. This is default

integer: Sets the variable/static as an integer; whole number.

float: Sets the variable/static as floating point number.

Description/Content

When "variable" is selected, this option will read "Description". Here you can just write a description for the variable and its usage.

When "static" is selected, this option will read "Content". Here you set the content of the static. This can be a long path, a name that might change some time or some other data. This is a bit like setting a global Windows environment variable.
