We moved a couple of lists from a SharePoint installation to SharePoint online, and I have to copy some workflows as well.
They are SharePoint 2010 workflows on the old SP installations, so I started "translating" them to SharePoint 2013 workflows, since that's the only option I have on the new site.
The main part of the workflow is exactly the same, the only difference is, that in 2013, there's a Stage wrapped around the Steps.
The inner logic is unchanged, while the list structure is unchanged as well.
There's a lookup field on the list, where I look up some data from a Customer data list. This field is what gets populated from the workflow.
Here's the workflow:
It get's an Input string was not in a correct format... error after Step3, when writing in the Lookup address local variable into the lookup field.
At Step3 I set the Lookup address to the following value:
[%Variable: Lookup address%];#[%Variable: ProjectID%]
This setting works in 2010 workflows without any problem, but it's giving me the format error in this setup.
Any ideas where this error can come from?
