simulink addition block error

i am getting the error as "Unable to determine signal dimensions. There is a loop consisting of 'srmlinearmodel/phase1/Add1' 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".

This is the only error in the model.

Did you try following the instructions to specify signal dimensions on one of your blocks (maybe on the Inport block)? Alternatively, you can insert a Signal Specification block in front of the Add block (one per input) and specify the signal dimensions on the block dialog.
