The COMBO gadget is a dropdown list where you can also type like a textbox.
If you only need a dropdown list and do not want the user to be able to type in a value, you need an OPTION gadget instead.

You are going to need to assign an open callback to a COMBO gadget or OPTION gadget, so please also refer to the Online Help about it.

I got the option box to populate, but I've been unable to figure how how to call a command. For example BetaArray1 = call 'beta 0"

OPTION .Beta 'BETA' WIDTH 5
!BetaArray[1]='0' 
!BetaArray[2]='90' 
!BetaArray[3]='180' 
!BetaArray[4]='270' 
!This.Beta.Dtext=!BetaArray

Hello again,
For OPTION gadgets and COMBO gadgets, the callback is not assigned to the gadget on the form setup part of the pmlform. It is set on the form constructor method.
Below is the example from the AVEVA Manual TM-1881 AVEVA Everything3D PML Form Design


I highly suggest to fully read the AVEVA Manual TM-1881 AVEVA Everything3D PML Form Design as there are sample codes there.
If your company does not have a copy of this manual, please contact your AVEVA Account Manager / Sales Representative if they can provide a copy. 
For the complete documentation reference for PML, please refer to the AVEVA Online Help, especially the Object Type Details section.

Is there any particular reason this wont button wont work?

BUTTON.CH 'MEASURE' CALL '!!GPHVIEWS.MEASURE('DISTANCE')'

Hello, can you try enclose DISTANCE argument with the vertical slash symbol | instead of apostrophe symbol '

• BUTTON.CH 'MEASURE' CALL '!!GPHVIEWS.MEASURE(|DISTANCE|)'

That worked! Thank you, I've been trying to figure this out!

You're welcome.
