I keep getting the same error in my script:

"Tried to access window, but not connected"

What does it mean and how to solve / work around it.

I think it has something to do with

New Window("MyWindow",

tt = V List Box()

);

For (i = 2, i <= N Col(InputTable), i++,

Expr(

tt << append(

H List Box( <Create Chart> )

)

)

);

Can someone tell me what is wrong with the expression... I get an emty window and an error message in the log file.

Thanx...

I don't know about that error message. But to populate the empty window the expression need to be evaluated. Or just skip the expr() wrapper.

Example:

InputTable = Open**(** "$SAMPLE_DATA/Drug.jmp" **)**;

New Window**(** "MyWindow", tt = V List Box**()** **)**;

For**(** i = **2**, i <= N Col**(** InputTable **)**, i++,

tt << **append****(**

H List Box**(**

Text Box**(** "Chart " || Char**(** i - **1** **)** **)**,

InputTable << **oneway****(** Y**(** Column**(** i **)** **)**, X**(** Column**(** **1** **)** **)** **)**

**)**

**)**

**)**;
