Erorrs in Bayesian estimation!

Ask for help:
I have some difficulties in find flaws in the following,Could someone help me?

It's hard to tell without having a model-file, but usually it means that a beta prior is not specified correctly. As a beta distribution is bounded between 0 and 1, a mean of 0.5 is e.g. incompatible with a variance of 0.5 as some values would have to be outside the support. Try to decrease the variance of all beta priors and see if it works then.

Thank you for your help!
I find some beta' distribution variance is set equal to 1.
