Script Flow

​🏃♀
 Script Run Order
Your script executes in order. The easiest way to think of this is like each step in your script is a stop on an assembly line. Each station on the assembly line can use anything built at a previous station, but not a later one. Something needs to have been built before it can be used.
If you want to print a variable, that variable needs to have been created before the Print to Log step.
Location variable is available in Print To Log step
If you were to switch the order of these two steps, then the 'Location' variable would not be accessible in the Print to Log step because it has not been created yet.
Step Sync
Each step in your script can hold one of two states:
1.In-sync: The outputs of the step reflect the latest changes to the selected or previous step settings or code
2.​
Out-out-sync: The outputs of the step do not reflect the latest changes to the selected or previous step settings or code
As you modify Module settings or write code, you will notice the following behaviors (as shown below): 
1.Changing Module settings or code on a selected step will result in the step being out-of-sync. 
2.Every following step will also marked with a
to warn you it is out-of-sync, as its outputs may be impacted by the selected step's changes.  
3.Pressing the sync button
or using the sync hotkey s will update the outputs of the selected step to reflect the latest changes, placing this step in-sync. 
4.Pressing the sync button
or using the sync hotkey s on each subsequent step will place them in-sync, or syncing the last step in your script will automatically place all previous steps in-sync.
As a general rule, syncing a step will place both the selected step and all previous steps in the script run order in-sync.
Pressing sync
on a selected step will execute code within a WayScript code module if it is a previous step, but will not execute sensitive actions from other modules, such as sending a Slack message or writing to a Google Sheet. These actions will only be executed by pressing ▶ on your script trigger or function.

 Variable Values
Like in other programming languages - the names of variables matter. Therefore, if you create a second variable with the same name, the value of the variable is overwritten.
​💡
 Different Variable Names
In the image below, a new variable, 'Location2' has been created. Therefore, the 'Location' variable with value "Brooklyn, NY" still exists.
There are Two Different Variables because they have different names.
​✏
 Overwrite Variable
Below, at step 2, the value of 'Location' is "New York, NY". The starting value, "Brooklyn, NY" was overwritten since the same variable name was used.
Brooklyn, NY has been overwritten because this variable uses has the same name.
