Microsoft Access Parameter Value pop up..

So having been thrust upon Microsoft Access after my colleague left and still, as a newbie, trying to come to terms with its workings and what it can do (will save that for another thread), I've got an issues cropping up with a Parameter Value whenever I try to pull up a report.

I've made a note of the identifier (Service User Experiences/Escalation Log.ID) but that identifier is the same name as a table form that I'm using? So is the problem within that? If so, how do I find out what the problem could be as there is a lot of data in there..

I've gone into Design View on that table form which lists all the fields in that table and looked at any word Escalation but seems normal to me..?

Help!
