Hi @adil1641
As mentioned before in this thread, the AMP plugin only has limited support for Twenty Fourteen at the moment, which means some of the functionality might be limited. We are working on it though, and you can follow that progress at https://github.com/ampproject/amp-wp/pull/1873.
Since you seem to have a heavily customized theme, I recommend you to have a look at our extensive documentation on how to build WordPress AMP sites. These guidelines show you how to validate your site, spot potential errors, and how to fix them in your theme. The ampproject.org website has also thorough guides that get you started with AMP.
One of the first steps you’d need to take is to remove all the custom JavaScript and replace the functionality with equivalent AMP components.
I also see that you are using Bootstrap. It looks like there a couple of guidelines available online that talk about using Bootstrap together with AMP.
Note that AMP is not just for mobile or desktop – it is for all your visitors.
I recommend you to start with the Paired mode in the plugin, fix any potential issues, and eventually turn on Native mode when all issues have been fixed.
Alternatively, there is also the Classic mode, which is essentially a “Reader mode” for your content.
