Count the number times a specific character appears in a text field

I have a multi-line text field where the data is delimited by commas.  The field can contain from 1-32 items.  Example: Chicago, Boston, Seattle.  I need to determine the number items in the field (in the example it is 3). 

 

I tried using split with a variable counter:   split(variables('Locations'),',')[variables('varIndex')]  This split sits in a DoUntil loop that increments varIndex by one.  However, when the index count exceeds the number of items, I get an error of 'out of bounds array index'.

 

How can I get a count of the commas or the items?  If I know the count beforehand, I can set the DoUntil to stop before it tries the split and throw the error.

 

Thanks!
