How To Exceed 255 Fields In A Table

I built an Access Database (at work in Access 2007) that has over a thousand records. It contains two subforms. I constructed it as follows:Built my MainForm (frmMain) to record report details (like serial number, title, date, time, etc.)This data goes to MainTable (tblMain) and there's only one record per reportBuilt and inserted SubFormNames (frmNames) to record names in report.This contains multiple records {has its own table (tblNames)} and is linked to tblMain/frmMain by serial number

Built and inserted SubFormCharacteristics (frmCharacteristics) to record events and characteristics using one text box for narrative (e.g. suspect robbed bank on 12th and Second Street), multiple yes/no check boxes (e.g. Perpetrator armed?, Multiple perpetrators, etc....), and several multivalued fields.This contains multiple records {has its own table (tblCharacteristics)} and is linked to tblMain/frmMain by serial number

I've reached the limit of 255 fields in the tblCharacteristics and I wish to add more characteristics.I created tblCharacteristics2 and tried adding those fields to tblCharacteristics but it doesn't work.I really don't want to create a frmCharacteristics 2 because all of my characteristics are alphabetized in frmCharacteristics and I would have to jump back and forth between the two subforms to enter my work. how I could link the checkboxes in tblCharacteristics2 to the narrative in tblCharacteristics (or tblCharacteristics).
