How To Execute A Dynamic SQL With Integer Parameter For Stored Procedure?

I'm having problem on trying to execute a query in stored procedure that has parameters as a integer. The parameter with the integer is in the WHERE clause. If I take out the WHERE clause, it would work. If I take out the parameter and replace it with a value, it would work. I have try using the CONVERT function to convert it to an integer, still no luck.

Error:  Unterminated String Constant.

What is the problem?

Set @strSQL='Select *
From
(
SELECT Row_Number() Over(Order By ' + @SortExpression + ') as Row_Count,Rank() Over (Order By ' + @SortExpression + ') as TableInfo_ColumnSort,dbo.EVENT_LOGS.EVENTLOG_ID, dbo.USERS.USERNAME, dbo.EVENT_LOGS.ITEM_TYPE, dbo.EVENT_LOGS.SCREEN_ID,
dbo.EVENT_LOGS.CHANGE_TYPE, dbo.EVENT_LOGS.IP_ADDRESS, dbo.EVENT_LOGS.CREATE_DATE,dbo.USERS.FIRST_NAME,dbo.USERS.Last_NAME
FROM dbo.EVENT_LOGS INNER JOIN
dbo.USERS ON dbo.EVENT_LOGS.USER_UID = dbo.USERS.USERID
) as TableInfo
Where Row_Count Between ' + @startRowIndex + ' and ' + @maxRowIndex + ' ';
Exec(@strSQL);
