Model using Gi* Stats tool is working on & off

I have created the most simplistic model ever (!!) for use in my organisation by my colleague, for us to save time.
See attached picture.

But for some reason, one minute it works, the next it does not.
All I want to do is:
1) Join my point data to my fishnets (so I have a count field refecting the number of point per fishnet cell) - I use the Spatial join tool - Temporary output
2) Run the Hot Spot Analysis (getis-Ord Gi*) tool (or Gi* script in the toolbox under Spatial Statistics) on the temporary output to get my z score.

I run it with data it does not work, re run it it works, then run it again and it does not.
I've lost track of what I'm doing woring... but it looks to me like I do the same thing.
I've also tried on different datasets but it does work on and off again.

When It does not work, I get the error message as shown in the attachment. Seems to be linked to the GI* Script.
Can anybody explain what it means... as I am not changing any attribute extent??

It is driving me nuts!

Many many thanks
