How to use Calculate Value for if then?

Question

I have looked through the documentation for using Calculate Value to act as if then in Model Builder, but am not connecting the dots. I want to Get Count to determine the number of rows. And then use that with Calculate Value to return TRUE else FALSE. So, if Row Count>0, then TRUE, else FALSE. Then use a While to point to the appropriate next steps. But how do I connect the Row Count to the Calculate Value? Obviously I'm missing a step or have made this too complicated because this is not feasible as described.

Please advise!

I apologize for not replying sooner - that was very helpful and worked, but I required additional complexity which forced me to Python. I needed to take the leap regardless. Thank you for your response and help!

I don't use model builder but I had a quick look. Something along the lines of (guessing the model builder syntax):

myfunc(%Row Count%)

def myfunc(input):

return bool(input)
