Multiple issues: Ref, autofill, and logical branching

[Work_Goscinski]

I used Google Forms to create my original app. (I don’t want to reconstruct it.)

I have workers that have to do 1 of 2 tasks at a machine: either check for coolant and record level OR go through a checklist of physical items.

As it existed, they typed the machine number. Next, they selected the type of machine. Recorded the refract number. Submit. Depending on type of machine (Dial, CNC, Special) brought them to part 2: their checklist. (Checklists for each type of machine differs.) Logical branching worked great.

Now come the errors:
I want to idiot-proof the app.

1. Operators would type in incorrect machine numbers. (Bad) OR
2. They would select the wrong type of machine bringing up the wrong checklist.

So, I changed the machine number input to Ref (I gave them a list of machines to pick from).
Then I changed the MACHINE TYPE to ref. This way it prefilled the type of machine depending on the number of the machine you chose.
BUT… Now the logical branching has disappeared. If you Select 236, it preselects Dial (as it should). But, I can only SAVE from this point forward. (Previously, I had NEXT which would take you to the proper checklist).
I don’t know how to get the NEXT button and logical branching back.
