I use the Labview 2012 with OPENG toolkit 4.0.1.9. 
  
Must the random number within range have the two input?   for example i want to generate random with 0~1, but i hav to add the 1.0 and 0.0 to the input. other with it shows the error below: 
  
  
Subvi 'random number within range__ogtk.vi' required input'low' is not wired
Subvi 'random number within range__ogtk.vi' required input'high' is not wired
 
does this vi have default inputs? did i do some wrong?
