Invalid operator all of a sudden

[Cabelo]

Hello there,

Today after making a copy of one of my prototype apps, I came across a bunch of errors. I was able to fix and understand dozens of them but there is one I am unable to understand and or fix (attached).

I did read the “Date and Time” and the “Math Expressions” articles again but Im still lost.

Can anyone see why an operator on this formula would have become invalid all of a sudden? Is (-) the only operator on this expression?

Thank you very much!

Nice to see I’m noticing the same things as the big boys do. Feels like I’m on the right path

Thank you very much! You were right, the type had changed from Date to Price by itself. It is now working, I really appreciate it! So, the operator (-) became invalid because you can’t calculate time using a price
