Hi everyone,  I'm using asp.net and when I click on a dropdown list on the page I’m getting the  error message:

  “JavaScript runtime error: Unable to get property 'call' of undefined or null reference”

Researching led me to believe it has something to do with the version of jquery I’m using so I tried doing …PM> Install-Package jQuery.Validation -Version 1.11.0… from this site:

https://www.nuget.org/packages/jQuery.Validation/1.11.0

I think the package was installed.  This is what the results looks like:

PM> Install-Package jQuery.Validation -Version 1.11.0

Attempting to resolve dependency 'jQuery (≥ 1.4.4)'.

Successfully installed 'jQuery.Validation 1.11.0'.

Install failed. Rolling back...

Install-Package : Updating 'jQuery 1.8.3' to 'jQuery 1.4.4' failed. Unable to find versions of 'Microsoft.jQuery.Unobtrusive.Ajax,

Microsoft.jQuery.Unobtrusive.Validation' that are compatible with 'jQuery 1.4.4'.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException

    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

I’m still getting the error message so I’m wondering what my next move should be.  Here’s a list of the scripts that I’m referencing on the page:

jquery.validate.min.js

jquery.validate.unobtrusive.min.js

 jquery.dataTables.js

MicrosoftAjax.js

MicrosoftMvcValidation.js

GradeValidation.js

jquery-ui.css

jquery-1.10.2.js

jquery-ui.js

Why am I still getting the error message after installing the validation package?
