Date Match?

[kueljo20]

Hi, would like to enter in the code the procedure checking whether the date chosen in the userform already exist in the list, as the row for each date may have got multiple entries. Therefore I would like to make sure that there is no blank space left. If the space already taken then put the date into the new row. Would really appreciate your help guys....
PLease find the file attached....

To be more specific. The userform in the file includes the date entry. The spreadsheet may have multiple dates in the list that may repeat. Each date may have multiple entries for different locations and different stores. What I would like to do is to chechk whether the date already exists. If yes then to check whether there is any space for the location entry, etc. If not, then to enter new date with this location and another specific info. ....Or there might be some different way (layout) carrying out similar procedure?
