===Flow Conditions===

Flow conditions are a set of [[commands:command_syntax|condition statements]] attached to a zone using the ''[[commands:zone_commands:zone_flowcondition]]'' command that need to be met in order for the zone to advance.

Note that the requirements for conditions are stricter than for standard command conditionals:
   * They can only use standard zone statuses and variables - [[concepts:variables:special|other]] variable types cannot be used.
   * They cannot use variable [[concepts:variables:references]]

If a zone is placed into a "wait" state using the ''[[commands:flow_commands:flow_trysingle]]'' command, the variables associated with that zone's flow conditions will be monitored - as and when they are all met - and a space appears ahead of that zone in the flow - the zone will advance without further input and will fire the command associate with the original query.
