easy asp help, cant spot error

Hi guys, you have answered many of my queries in the past so thanks on that, but i need help on this.

i have  a simple form on a page passing a score, level and playername

the code below is on a page that should write to a db. i have done this before on my own site and have compared this code with other code and it looks fine, however, i keep getting a syntax error in INSERT INTO statement. I have played with things and taken the numbers out and it seeems to be ok just insert the playername field. so prob something to with the numbers?

any ideas?

<%

level = Trim(request("level"))
score = Trim(request("score"))
playername = Trim(request("playername"))

Dim objConn
Dim strConnectionString

strConnectionString = MM_fr_record_webtest_STRING
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.open strConnectionString

sqlstring = "INSERT INTO highscores ( level, score, playername ) " &_
"VALUES (" & Replace(level, "'", "''") & "," & Replace(score, "'", "''") & ",'" & Replace(playername, "'", "''") & "')"

objConn.Execute (sqlString)

%>

Cheers

Hi

my original code was without all the 'replace' bits and was simply

"VALUES (" & level & "," & score & ",'" & playername & "')"

and still didn't work

level and score are numeric:

level = 3

score = 3660

playername = john smith

level< size=5 name=level>
score< size=10 name=score>
player_name< size=50 name=pname>
< =submit value=go>

as i say changing the sql code so i am just inserting playername is fine, i can do that, it just fails when i try to insert a number

yup done that before

i get this

INSERT INTO highscores ( level, score, playername ) VALUES (1,2,'mark')
