i bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.
I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404 -

Hi I'm a total novice, as you will see. But Iam trying to use template of an employee schedule but when I try to add extra columns it does not add the preset formula with it, so it works out total hours and total pay? If any one can help please before I throw it through the window!

Hi Grum,
If the formulas aren't filling to the new column, you must have changed something in the template since you first opened it. Numbers is rather fussy about filling row content in columns as they are added. Only rows with the same expression in every Body Column will fill when a column is added. Just as an experiment, start a new Employee Schedule document from the Template Chooser and then add a column by clicking the Add Column handle in the upper right corner of the table. If that works, as it should, then think about what might have changed in your working document to disconnect that feature. Maybe we can figure it out together.
