I have created a workflow using SharePoint designer. The workflow was designed to alert via email individuals associated to the list items created or updated. Within the workflow, I have a hyperlink created within the email that allows the user to click on the word "HERE" which will pop open a window with the list item to view and modify.  The issue I am seeing, when I create the workflow, it works for a time then starts to fail and I get the following screen:

Error

An

Go back to
site

When the link works, it populates the following URL:

https://blah.blahblah.blah.com/sites/IT_infrastructure_Services/globalnetworkoperations/_layouts/listform.aspx?PageType=4&ListId={E515D6BD-B514-47BA-8A5F-10C190F8F5F5}&ContentTypeID=0x01009E1D7CFC058403469C8EBE09D2480939&ID=28

When it starts to fail, the link looks like:

https://blah.blahblah.blah.com/sites/IT_infrastructure_Services/globalnetworkoperations/_layouts/listform.aspx?PageType=4&ListId=\{E515D6BD-B514-47BA-8A5F-10C190F8F5F5\}&ContentTypeID=0x01009E1D7CFC058403469C8EBE09D2480939&ID=28

What I do see is that the hyper link starts to generate slashes:

\{E515D6BD-B514-47BA-8A5F-10C190F8F5F5\}

I cant understand why my workflow will start to creep.

I am extremely new at this so I will take all the help one can provideHere is my code:

The HERE link code is:

https://blah.blahblah.blah.com/sites/IT_infrastructure_Services/globalnetworkoperations/_layouts/listform.aspx?PageType=4&ListId=\\\{E515D6BD-B514-47BA-8A5F-10C190F8F5F5\\\}&ContentTypeID=0x01009E1D7CFC058403469C8EBE09D2480939&ID=[%Current Item:ID%]

Thx all

I am still looking for advice.  I have not found a solution to this issue yet.  I know it works, as I have another workflow set up similar and it has been working fine for months.
