Code fix

NEED SOMEONE WHO CAN MAKE URGENT CODE FIXES RIGHT NOW. The attached file interacts with our database. You can see the live file at www offersinthetimes com / [login to view URL] In need it fixed so that: 1. when it is first opened and neither Permanent nor Supply are selected, then nothing appears on the right hand side of the page. By selecting one of these 2 options, the correct the correct content already appears, but I want it empty when nothing yet selected. 2. when you enter the first part of postcode, a drop-down list of matches appears. But this is not working on all browsers. I need a quick solution that will work across all browsers. 3. when Permanent / Supply selected, the right hand side should appear with correct content. This works on some browsers but not on older browsers (nothing changes on older browsers).
