Hi i need some help with starting with the VSTA.
I want to store data in a variable using the block array functions in order to display data with the extended trend. However i succed with writing and reading data using these two lines

this.Variables().Item("Testar_int2").set_Value(0, 300);

string tal1= this.Variables().Item("Testar_int").get_Value(0).ToString();


However i dont now how to use the block array function. Any one that have done this before?
Thanks in advance
