Var Syntax

@Var[name] is the notation for Workbook variables whose names contain spaces or were auto-generated by InVision components (Data Flow, Form Element, Script). For variables you create yourself, prefer standard names accessible via AppVariables.Name.

Reading

@Var[…] can be read anywhere in an Eaze expression:

CONCAT("Selected: ", @Var[Last Row Clicked].ProductName);
OpenBrowserWindow(CONCAT("http://api.company.com/appendix/", @Event.Data.ProsjektID));

Writing

Assignment to @Var[…] is only valid inside Execute Expression actions — not in cell calculation formulas:

@Var[My Factor] = 12.4;
@Var[Last Row Clicked] = @Event.Data;
@Var[Last Row Clicked].ProductID = @Event.Data.ProduktID;

Clearing and generating IDs

@Var[Name] = null;          -- clear the variable
@Var[Name] = NEWID();       -- assign a new GUID

In JavaScript action handlers

When using JavaScript action handlers (2025.5+), reference @Var[…] variables via this.appVariables:

const val = this.appVariables["@Var[My Variable]"];

See JavaScript Code-Behind for the full Eaze → JS translation reference.
