Hello friends, after several months of work with my script I have decided to ask for help, hoping that among all can help.

The situation is as follows:

With that command serious type "/ did -...." Could trigger checkbutton in that order list changed with the mdx.dll

I am the only basis that I am not able to make the statement that haria that will trigger checkbutton without clicking the above, I want to begin the dialog, if a variable has a certain value, activate The checkbutton.

I enclose a picture to see where I want to apply this command, thank you very much
