MATLAB: Undefined operator / for input arguements of type cell.

arithmeticarraycalculationerrorfor loopundefined operatoruser input

I realize this question may have been asked a billion times, but I can't for the life of me see why its popping up with my code. I'm calculating the maximum value in a data set 'bridge1Load' through this loop:
maxLoad1 = 0;
for n = 1:length(bridge1Load)
  for k = 1
    if bridge1Load(n, k) > maxLoad1
      maxLoad1 = bridge1Load(n, k);
    end
  end
end
and my bridge weight is a user input from:
bridge1WeightInput = inputdlg('Please enter the weight of bridge #1','Bridge #1 Weight');
I'm trying to calculate the strength to weight ratio via:
s2wRatio1 = maxLoad1 / bridge1Weight;
but I keep getting the error stated above.

Please ignore this rather silly question, I had to use str2double.....
