Calculate field not functioning

Question

For some reason, when I run the calculate field tool, it doesn't calculate the field. I was having success with this for quite a bit and it suddenly stopped working.

I have a feature class that I have added fields to. All are Double and numeric. I take Field A and divide by Field B to enter result in Field C. However, after the calculation is done, the field remains <null>.

Any insight would be appreciated.

I had total success with this method. However, I buggered my data and needed to start over. I am quite frustrated.

Ok. I loaded th eoriginal shapefile into a different project. Ran CopyFeatures and that turned it into FGDB. Added fields, calculated and it worked.

The table is too big to show all of the fields. The expression is simple: !TotalAssmn! / !Acreage2!

I thought I had an idea of what happened so I was doing some testing and it seems to work randomly at this point.

Just ran a calc and it worked fine, so a screen grab of the table (and field contents) and calculator expression might be in order.

Everything sounds fine.  But seeing would assist in ruling out some of the other suggestions

Prior to putting in a call to Tech Support if all else fails try...

* Repeating a calculation on another table, maybe even in another project using different data to rule out project and data issues

If that fails too

* Windows Control Panel... Add Remove Programs, Select 'Repair'.

If nothing changes and all is as described, file a case with tech support.d
