I am pending a promotion in these aircraft and I have an issue with the VOR in these aircraft. Tuning the VOR in the NAV1 and 2 radios are fine but when I look to my compass the line that tells you how on-course you are isn't showing up. it looks like this -----__-----> it doesn't show up. I have confirmed that my nav isn't set to GPS and I know that the radios are tuned correctly. I need help.

Are you talking about the VOR needle in the MFD? Just off the top of my head, I'm wondering if you aren't in range of the VOR yet. Just a thought. I've never had a problem with the VOR needle in the fleet 738 if I was in range of the VOR.

I have confirmed that i am in range of the VOR station. yes that is what its called VOR needle in the MFD. By the way i have fs2004. here is the procedure that i go through to enter the VOR station there might be something wrong with it
1. Go to nav radios
2. in NAV1 tune the VOR frequency
3. hit the switch button so the VOR frequency isn't in the standby box anymore
4. confirm that the switch isn't set to gps instead of nav
5. look at the MFD display
6. it isnt there! all i see is (------- ------>) and not (--------_____----->)

Have you identified the VOR? Tune it, then listen for the morse code and make sure it matches what's on the chart.

what is not showing up is the line that almost parallel to the little airplane in the center that tells me how on- course i am. in other words the OBS needle.

I may be wrong about what you're refering to, but that looks normal to me. The short white vertical line in the middle (and slightly to the right) will joim up with the two white arrow halves when you are on the radial you've selected.

Remember too that VOR stations are directional radio beacons. Not only do you tune the VOR station, but you set the radial as well, relative to how you want to fly to the VOR or away from it for vectoring. So no matter how much you are in range of a VOR, if you don't have the correct relative radial tuned, that line in the middle may never match up.

Thomas,
From the picture you posted it looks like you on a heading of 325 attempting to intercept the 318 radial of the VOR. The bearing to the VOR is 284 so you should intercept if you stay on the same heading. This will be a 'hard' left turn to intercept the 318 radial since you are only 5.3 miles and 1 minute 3 seconds from station passage.
If you are attempting to fly direct to the VOR then twist your OBS (Omni Bearing Selector, V1+- or V2+-) until your course line centers on the selected radial then fly that heading to cross the VOR. The CDI (Course Deviation Indicator is what you are referring to with regards to the (------- ------>) and (--------_____----->) lines you mention). This line simply shows how much you are off course from the chosen radial you selected. If it is deflected to the right then you'll need to turn right to intercept, same thing if it's deviated to the left.
Depending on altitude, be aware that there is a 'cone of silence' above the VOR when you are close to it where the needle will deflect fully to one side or the other during station passage. In fact, if you were at 35,000 ft when you snapped this picture then you would be getting a deflection already since the DME distance (5.3 miles) is the 'slant range' distance to the VOR (and will never be zero unless you are at ground level). Navigation very close in to the VOR can be tricky since the needles will be all over the place during station passage.
The proper way of crossing is to pick up your inbound course, center the needles and fly that heading (compensating for wind drift). When you are about 10 miles from the VOR, dial that heading in and engage Heading Mode until you are about 6-10 miles on the other side of the VOR then re-engage NAV mode on the selected outbound radial.
Flying around in a B727 without an INS or GPS will give you a quick introduction to VOR navigation
Post a full-panel view of your problem with a detailed description of what you are trying to accomplish and we can try and be more help.
