Web page need to scroll to see an element

Sorry I should have been more specific.

I want to do a while loop to scroll this page.FindElement(".ag-body-horizontal-scroll-viewport") until this is present. I set it to continue on errors but I get 

Unable to find the object "(//div [@col-id='XePatientVisit.WorkID.XeWorkflowInstanceState.0.WorkState'])[2] ". See Details for additional information.

If I have a bigger screen it fails to find the object.

I have it set to continue on errors so why am I getting an error

while Project.Variables.queue == 'blank':

    x=100+100
    page.panel19.Drag(x, 5, 86, 3) or  I try page.panel19.Click()

    Project.Variables.queue= page.FindElement("(//div [@col-      id='XePatientVisit.WorkID.XeWorkflowInstanceState.0.WorkState'])[2] ").contentText
