You cannot do something like this: 


Sub RetrieveDetails(lblQuestion as label, _
lblAnswers as label, _
lblViewCount as label, _
lblLastUpdated as label)

instead of the above if you really want to assign the text to the label you can do something like this:

Sub RetrieveDetails(lblQuestion as String, _
lblAnswers as String, _
lblViewCount as String, _
lblLastUpdated as String)

And later assign the values to the Label.Text:

looks like you're passing in the text value, but in your sub definition, you are saying you will pass in the actual label, so i think if you pass in the label instead of the .text value, it should work like you want it, like this:

myGetRandom.RetrieveDetails(lblQuestion, lblAnswers, lblViewCount, lblLastUpdated)

hope that helps,
