In B2 of the Summary sheet, change the formula to this one:
=IF(ISNA(VLOOKUP($A2,INDIRECT("'"&INDEX(Areas,MATCH(TRUE,COUNTIF(INDIRECT("'"&Areas&"'!A2:A50"),$A2)>0,0))&"'!A2:Z50"),COLUMNS(B$1),0)),"",VLOOKUP($A2,INDIRECT("'"&INDEX(Areas,MATCH(TRUE,COUNTIF(INDIRECT("'"&Areas&"'!A2:A50"),$A2)>0,0))&"'!A2:Z50"),COLUMN(B$1),0))
hold the CTRL and SHIFT keys down and press ENTER.. You should see the { } brackets reappear... now copy over and down as far as you want...
This will accomodate for up to 50 rows in each sheet and 26 columns in each sheet.
When you insert new columns in the other sheets, you may need to many adjust the headings in the Summary sheet.
