000 to 999 counter Circuit LCD Not working Help

I am trying to outline the design for my project for my circuits class I am pretty new to Multisim, but I have tried everything to get the 7 segment 4 digit LCD and or 3 7 segment Hex to display properly I am not sure if its something wrong with my circuit orthe software. I hooked a logic analyzer to the outputs of the counter 4516B IC so I know that it is counting. There must be a error in the way I am connecting my driver 4543s Please help so that I can begin physically building this circuit and wire wrap.
Thanks in advance.

Have a look at the attached file; I've isolated the two parts you mentioned so that you can see how they work. Press the key A, B, C and D on you keyboard to control the inputs DA to DD and you can see the results on the 7 segment display.
U17, I've turned on the symbol pin name so that you can see which pin is which. A1 to G1 are part of the first 7 segment LED.
Here is a datasheet for the 4543:

I hope this helps.

    Hi,
    the settings are gone, i guess. But even worse, I cannot get the iPad2 to play Full HD thru the Apple digital AV adaptor using apps that support  (and advertise this), like AVPlayer HD. This definiteley used to work before one of the last iOS upgrades. (I am now at 5.1.1).

    Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

    It all depends on the codec the file uses, Karli.
    What model of camcorder is this video coming from?
    Are you working on a Mac or a PC? Have you got the latest version of Quicktime, per the program requirements? When you started your project, did you select the settings for a DSLR at 720p? This is a vital step since it will activate the components your computer will need to work with many of these types of files.
    BY THE WAY, KARLI--
    PLEASE do not post the same question more than once on this forum! You've already got a thread going with this same question and several responses posted. It's very confusing when you post the same question a second time and start a whole new discussion.

    Find the section that applies to your computer, and follow the instructions.
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

    If you only restored from backup, restore to factory defaults/new iPod.  If you then still have the problem it is likely a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    hi all,
    I am doing an onsite poc on customer site, and configuring and proxy service on OSB(11.1.1.5) using ftp , but it just not working, not picking files in the specified folder, no error message. seems it can connect and login, but just not picking the files, though I set the mask to *.*, poll interval 3 seconds. any tricky? someone can help?
    I've read all the documents abt ftp transport, and I can configure file proxy, ftp business service successfully.
    thank you very much in advanced.

    no log still, for DEBUG.
    error will throw in log only if I set the wrong user/password.
    seems it connected to the ftp server, but just not picking the files there. I don't know why. I doubted it's the problem of the path setting, but it's the same for phsical path and relative path. not working.
    help...........
