How I can fix this "Signal Dimension" error message ?

Dear friends, I get the following message when I run my simulink model."Unable to determine signal dimensions. There is a loop consisting of 'sim/Mux' that cannot be resolved because signal dimensions are defined by a cyclic relationship. Specifying the signal dimensions on Inport, Mux, Selector, Demuxes will help resolve signal dimensions in the loop. You can also use the Signal Specifications to define the signal dimensions."Any kind help ?

You may use Simulink/Signal Attributes/Signal Specification block. Specify number of dimensions like that is shown on the picture. [1,3] means that the signal is 1 by 3 array.

I forgot to notice that you need to place that block after the Mux block.
