How can I prevent negative numbers?

I have built an overtime field that relies on daily hours. I thought there was an option for Greater Than but I can only find Equals and Not Equals. 

Ideally, I would want the Daily Hours field to be ignored by the Overtime field if it is not Greater Than 8

On another note, are their tiers of support when we move into subscription status?  

Hi,

You can use the MAX math function e.g. max(0, result). This will turn negative numbers into 0.

Example:

Things to note: make sure the comma is not a text string (brown). It should be black to perform calculations.

Hope this helps!
