Model parameters custom gui

I am little bit unfamiliar with flexsim syntax, following user manual of flexsim4.5.

I am using three queues in my model and want to pass max content parameter of each queue through custome gui when you press button ok on the custom gui.

I have added coldlink control attribute into edit button and configure its script to
@>objectfocus+Queue13>variables/maxcontent where as custom gui attributes objectfocus to Main:/project/model and same for view focus.

I have tried many script nothing is linking custom gui to model object variables.

Please help me.

You're very close. You just need to add a forward slash after the '+' sign, like this:

@>objectfocus+/Queue13>variables/maxcontent

Check out the attached model for a working example. The custom GUI is attached to the Control button.

Thanks, you made my life a bit easier.
