Sad Shiny App won't work for Logistic Reg MLM Power Calc


Less is more. Stay pure. Stay poor.
I am trying to use a shiny app for a simple logistic regression multilevel model power calculation. But every time I click on the 'Covariates' option to change it to '1', I get 'disconnected from server'.

Is there anyone out there at all that can walk me through this.

I have 47 subjects with 3 measures collected and one I guess 1st, level covariate (?), time. I wanted to see if the binary outcome changed across time for the 3 measurements. I can provide more information. I believe the app author ( @spunky ) once mentioned that if the app was failing, a person could use the underlying code.
