Fsbuild-2 Flight Planner

I'm hoping someone could assist me with creating a VNAV button. Specifically, I'm trying to add the button in the main panel of the NPSIMPANEL 737NG. Unfortunately, when I add the guage, as specified in the setting.pdf, nothing appears in my main panel. I would greatly appreciate any assistance anyone can offer.

[Window00]
Background_color=0,0,0
size_mm=1024,768
position=7
visible=1
ident=MAIN_PANEL

gauge00=B737NG!B737NG Main, 0,0,1024,768
gauge01=B737NG!B737NG Primary Flight Display, 147,568,160,170
gauge02=ISG1!HW_B737_ND, 358,568,160,170
gauge03=B737NG!B737NG EICAS ENG, 681,568,160,170
