How to display number of form submissions in a form?

I am new to Zoho Forms and still learning after converting from JotForm.  How would I go about displaying the total number of entires in a form?  For example, if there are 40 completed entries in a form, how do I display this number (40) in the actual form itself?  We typically limit the number of entries to 50 and our members like to see how many entries are still available until it's full so in our previous forms product there was a system variable we could use to display the number of entries and then calculate the variable from the whatever number I have set the limitation to using a formula field.

Does Zoho Forms have anything to enable me to make the same calculation of "Spaces Available"?
