Tips for Preventing Errors

The following tips might help you prevent problems while scripting.

Provide closing HTML tags, even if you think the browser will process the tag without its closing tag. For example, you might think that the browser will close an <OPTION> tag automatically, even if you do not include the </OPTION> tag. However, many browsers will not.
Be aware that the values returned by some procedures, methods, functions and properties vary depending on the situation or context. For example, the ADO record set object supports a property called RecordCount, which is documented as returning the number of records affected by a statement. However, the value returned in this property depends on the database. Microsoft SQL Server does not return a useful value in this property in certain cases, so you should not rely on it in your script. Instead, you should check RecordSet.EOF, using script such as the following:
```
Do While Not RecordSet.EOF
	' Process here
	RecordSet.MoveNext
Loop
```
