First you need to learn how to ask a question here on the APEX support forum...
Change your forum handle to something more friendly.
Next include relevant information, like APEX version, browser being used, Database server?
Also, since you are newcomer to APEX, don[t you thin k you MIGHT want to learn how to develop in the product BEFORE starting to design your own themes? (A rather complicated project even for experienced APEX developers..)
There are also a number of great places to visit to save you reinventing the wheel.
