Need help Initializing strings

Need help Initializing strings

Need help Initializing strings

(OP)
I have three strings defined in code that i need to initialize.  in these three strings i am building a record key from data in an access table that will be used in another system (MAS90 accounting system).  My trouble is that after processing the first record in the table, when processing the next record, the "strings" still contain data from the first record key that was constructed.  i think i need to clear these strings out before starting on the next record but i am not a coder and don't know how to do this (can't find the instruction that does this).  can someone help ?  code i am using is below,
Thankyou so mucn !
Paul
 
Public Sub UpdateKey()

Dim db As DAO.Database
Dim rst As DAO.Recordset
Dim strSize As String
Dim strBoName1 As String
Dim strBoName2 As String
Dim bytCount As Byte
Dim bytPos As Byte
Dim strKey As String

Set db = CurrentDb
Set rst = db.OpenRecordset("SELECT * FROM AllItemsConsolidatedTable")

Do While Not rst.EOF

'Create Size string from field, eliminating spaces

    For bytCount = 1 To Len(rst!BriefDescription)
        If Mid(rst!BriefDescription, bytCount, 1) > " " Then
            strSize = strSize & Mid(rst!BriefDescription, bytCount, 1)
        End If
    Next bytCount

'Find where a "'" is and grab the first 8 characters of that
 
   bytPos = InStr(rst![ItemName], "'")
    If bytPos <> 0 Then
        strBoName2 = Mid(rst![ItemName], bytPos, 8)
    Else
        strBoName2 = ""
    End If

'Create Botanical Name string without spaces (not working)

    For bytCount = 1 To Len(rst![ItemName])
        If Mid(rst![ItemName], bytCount) <> " " Then
            strBoName1 = strBoName1 & Mid(rst![ItemName], bytCount)
        End If
    Next bytCount

'Grab what is left over of the botanical name (works)

    strBoName1 = Left(strBoName1, (30 - Len(strSize) - Len(strBoName2)))

'Assign the key string

    strKey = strBoName1 & strBoName2 & strSize

'Edit the record

    rst.Edit
    rst!MAS90ITEMKEY = strKey
    rst.Update

'move to the next record if there is one

    If Not rst.EOF Then
        rst.MoveNext
    End If
Loop

rst.Close
Set rst = Nothing
Set db = Nothing

End Sub

RE: Need help Initializing strings

I only glanced at this quickly but how about trying"

'move to the next record if there is one

    If Not rst.EOF Then
        strBoName1 = ""
        strBoName2 = ""
        strSize = ""

        rst.MoveNext
    End If
