Fusion Script Error

[Bear22]

Guys,

Trying to write a command script for my Versa pump where if the pH (dosing NAOH) exceeds 8.20 the outlet will shut down. When pH falls below 8.00 the Versa resumes normal operations.

Fusion doesn't like this script below and keeps giving me an error message:

Fallback ON
Set ON
If pH > 8.20 Then OFF
If pH < 8.00 Then ON

Suggestions?

TIA

P.S. ChatGPT was of no help with resolving this (no surprise)
P.P.S. is there a Fusion online resource that can read-proof-trouble shoot instructions?

I don't own an Apex or Versa pump, but are you sure your pH probe is actually called "pH"? If you have renamed it you might need to adjust the name in the script as well.

I found this tutorial on Reef2Reef maybe it has some useful information as well: https://www.reef2reef.com/ams/neptune-apex-programming-tutorials-part-1.685/

And here is another quick guide from the Neptune systems forum:
