Drupal 7.x

Hello here are my questions

1)if i have 2 seperate drupal7 intranet application Application_1 and Application_2 with seperate databases.
Is it possible to fetch data from Application_2 when i am trying to insert a node in Application_1?

2) For these 2 seperate appalications is possible to have a centralized permissions for the users. One database for controlling access to the permitted actions a user can make?

I have a content field for salaries for candidates.

I have an exposed view block that allows them to sort high to low salaries.

How do I get views to sort £100K at the top and not £75K?

I considers £100K less than £75K as it's reading the 1 first.

I have it as a text field, however there are decimal and integer field types I could use.

What should I do to get this working correctly?

Thanks

I'm new to Drupal but not to installing scripts/software for website creation. I've freshly installed the latest Drupal (7...) and the main core has been working fine. I've been trying to install Ubercart, of which you are required to install various other modules beforehand:

Rules
Views
Ctools
Entity

Had various problems activating some of these in the form of the dreaded Error 500 Internal Server Error. Eventually, with A LOT of patient refreshing, I got the site up and running.

I then had an 'admin status report' notification which told me that one of the modules that I had installed directly from the Drupal website, (ColorBox), was out of date. Downloaded it, updated it, etc, bang, same thing again, Error 500. I've since completely deleted this module but still have the Error 500 problem on my site, as below:

HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfil the request.

My site is: http://pinkgarden.co.uk/mp it's a test site so that I can figure Drupal out and see if it can do what I'm trying to achieve. So far, I'm not having much luck as it keeps going down...

Am I doing something wrong? Why am I receiving these errors frequently? I'm not installing tons of modules, and I only install and activate things one by one. Once they work ok, I then try another.

I am able to use the WYSIWYG CKeditor when I create new content. However, when I try to go back and edit the content, the content panel shows the html that was created by CKeditor (version 7.x-1.9), but the CKeditor is not visible on an edit.

I have tried making changes to the CKeditor configuration, but nothing fixes the problem.

Hello everybody..
I installed the ACL module on a test installation of drupal and it works fine but when i applied it on a production site (on the same web-server,same mysql-server ) it doesn't work..i can't rebuild permission and it seems that the module has no effect ( especially when i disable viewing content for a specified content type ) .
Please any body has an idea to overcome this problem ...
Thank you very much
