Hi repley! You have perhaps typed the text in some other programme in your computer which is not compatible with the Forum thread. Consequently, after pasting in the Forum thread, the text has appeared with unwanted matters making thing difficult to indentfy the actual text.

Your question is about appropriate use of present ferfect and past simple. This always create doubt perticularly in the beginning stage. The simple rule here is: Choosing whether to use the Present Perfect or Past Simple usually depends on whether a definite or indefinite time is used. If a definite past time is used, use the Past Simple, and if there is no time given use the Present Perfect
