Reopen Block UI Styler and add values

I create a user form using Block UI Styler that has one double and one integer( two textboxes) then I exit the Block UI Styler.

Now I need to add one extra textbox to the same UI Styler.How do I re-open the same UI from NX so that I could add in the same design?


Go to the Block Styler application, choose "open" from its File menu, and choose the dlx file you created.

Thank you so much..It worked :)
