Very Strange

I have a break (at least I think that's what you call it when the code stops at a point and highlights the code concerned) that has me baffled. As you can see from the attached the offending code item has a value and should then run the code accordingly. But it breaks at that point.

I know that this is something silly I am missing but I don't know what.

It's run from a button on a form that opens a report. It must be something that is not yet recognised, saved or refreshed because when I close and reset the code window and click the button again it runs fine. It only happens when I have just opened the form and never again regardless of which record I move to.

The frustrating thing is that according to the little pop up box it appearers that the "FPMS" has a value.

Or perhaps it is an erroneous error caused by something else.  It sometimes asks for a parameter value, It takes this from the form which has the button. So the button opens the report which opens a query that is looking for a parameter which is the item number of the form that has the button. How can it not get that information when it is right in front of my eyes
