| Property | The attribute that is to be compared. |
| Operator | The comparison operator to use |
| Value | The value to compare to |
else if variable
Add an additional if condition to an existing control structure block, referencing a variable.
| Argument | Description |
|---|---|
| ThisValue | The value to set variable to (input or another variable) |
| ThisVariable | The variable to set the value of. |
| Operator | The comparison operator for comparing values in the table against the input value. |
end if
Marks the end of a IF/ELSEIF/ELSE structure.
end repeat
Marks the end of a repeat structure.
end switch
Marks the end of a switch structure.
end try
Ends a try block.
exit repeat
Exits the repeat current repeat loop.
exit script
Exits the current script.
finally
Runs all lines below it, inside a try structure, whether there is an error or not.
if property

| Argument | Description |
|---|---|
| Element | The element to have its property compared. |
| Property | The attribute that is to be compared. |
| Operator | The comparison operator to use |
| Value | The Value to compare to |
if variable
Creates the first line of an if condition referencing a variable.
| Argument | Description |
|---|---|
| ThisValue | The value to set variable to (input or another variable) |
| ThisVariable | The variable to set the value of. |
| Operator | The comparison operator for comparing values in the table against the input value. |
next repeat
Skips the rest of the repeat control structure and returns to the top for the next repeat.
repeat
Repeat a code block n number of times.
| Argument | Description |
|---|---|
| Number | Specify the number of times the repeat block will run |
repeat over array
Repeat loop over the indexes or keys of an array.
| Argument | Description |
|---|---|
| RepeatOver | Repeat loop over indexes or keys? Indexes are numeric, keys are strings like IDs. This action will repeat over every index in the array in order from lowest to highest.

| ArrayVariable | The array variable whose indexes or keys you want to loop over. |
| ArrayPath | The path of the array key which contains the indexes or keys you want to repeat over. Expressed in ‘/key1/key2/’ format. |

switch property
Begins a switch block where the value of a property is compared.
| Argument | Description |
|---|---|

| Property | The attribute that is to be compared. |
switch variable
Begins a switch block where the value of a variable is compared.
