    Easy. Convert it to a list of numbers, and have them pick one. Kind of like a cell phone does

    Assign the value of the InputBox to a string. Check the string to see if it IsNumeric.

    Rsuh, please don't just slpa code together and post it here, without any sort of explanation - hence the confusion. I can suggest use AND instead of OR

    Rush. Some more forum ethics here :

    First, use the Report post feature only to report spam or insulting posts. That is all that will get removed.

    Second, You have edited your first post in this thread, rendering this thread entirey completely and wholely useless.

    This is a forum, where questions are asked and questions are answered. That is the whole definition of the word forum. Now, people having the same problem as you will never ever find their answers because of your selfishness. I will Go back, and edit your first post to reflect the original question again.

    Please don't do it again, and please only use the report post feature to report spam

    Hannes, &H100 is a Number. Why do you think cellphones don't have you type time or date fields out by hand?
