well, graff, unlike the other folks who replied above (including myself), you saw a post that is totally different from what they saw (and from what I saw). There was not a single line of code in the original post, no sample data, no example, almost nothing... The post had just 2 lines.

It is good that flora now provided that information requested, but that information just wasn't there when the "other folks" replied.

To flora: nothing against you, you are new here and are really welcome, but when you change your post, it is considered good practice to leave the original content unchanged and add new elements clearly as new stuff, or at least to explain what you have changed to the original content.
