@Russ_Thomas, I saw your solution for similar thing here [link](http://forum.katalon.com/t/how-to-access-a-map-stored-in-globalvariables-map/30919)

how can I create globalvariable for map type at runtime. Currently I am using the following script to create globalvariable for string

> static void addGlobalVariable(String name, def value) {  
> GroovyShell shell1 = new GroovyShell()  
> MetaClass mc = shell1.evaluate(“internal.GlobalVariable”).metaClass  
> String getterName = “get” + name.capitalize()  
> String setterName = “set” + name.capitalize()  
> mc.‘static’.“$getterName” = { → return value }  
> mc.‘static’.“$setterName” = { newValue → value = newValue }  
> mc.‘static’.“$name” = value  
> }
