Option Strict On requires all Function, Property, and Operator declarations to have an 'As' clause
A declaration contains a declared property or function return without an As clause. When Option Strict is On, every variable, property, procedure argument, and function return must be declared with an As clause to specify its data type; for example, Dim MyNum As Short.

To correct this error
Check to see if the As keyword is misspelled.
Supply an As clause for the declared property or function return, or turn Option Strict Off.
