vba - Using a Converted string in CurrentDB.Execute or DoCmd.RunSQL? -


table school year has (in order):

id primary key

description short text in format of xxxx-xxxx

current year boolean (only 1 checked @ time)

i'm creating button appends new year cycle table increasing year one. ex: 2009-2010 -> 2010-2011

however, current code, i'm doing string int conversion , string it's not staying back. table appends new data fine, data wrong. id , current year accurate, description mathematical calculation , becomes -1. (as in 2010-2011 = -1). however! msgbox display displays full year string.

how go fixing issue? in advance.

here's code: 

private sub newyear_click()      dim iyear integer     dim sdesc string     dim idesc1 integer     dim idesc2 integer     iyear = dcount("id", "school year") 'row count primary id number     sdesc = dlookup("description", "school year", "[id] =" & iyear) 'grabbing string     idesc1 = cint(right$(left(sdesc, 4), 4)) + 1 'increasing year 1     idesc2 = cint(right$(right(sdesc, 4), 4)) + 1     sdesc = idesc1 & "-" & idesc2     currentdb.execute "update [school year] set [current year] = false" 'turning off current year      dim teststring string 'did in hope fix problem, didn't     teststring = "insert [school year] values (" & iyear + 1 & ", " & sdesc & ", true)"     currentdb.execute teststring     msgbox "school year set " & sdesc end sub
