stateflow expected a scalar error

Hi, I am getting this error when trying to compile my stateflow design

Expected a scalar. Non-scalars are not supported in IF or WHILE statements, or with logical operators. Instead, use ALL to convert matrix logicals to their scalar equivalents. Transition '[moduleSelected]' (#1064) "moduleSelected"

moduleSelected is an input defined as a boolean

I am at a loss why stateflow is giving me this error for this simple check. I have attached a picture of the statemachine. Thanks

Hi,

It seems that the input "moduleSelected" is vector or matrix. In conditions, vector is not allowed.

Thanks.
