I have a form with the question

 

10. If yes, please rank the below barriers in order of their significance, 1 being the main barrier to the development of the market and 5 being the least significant

i. Confusion and lack of knowledge

ii. Inexperience in trading property derivatives

iii. Illiquidity

iv. Index smoothing

v. Pricing issues

 

I want to use php to make sure that one of the entries isn't entered twice. An each individual has a ranking.

 

Any pointers appreciated

thats is not what i am looking for. The question asks the user to rank all 5 options. That order is sent to my form processing page.

 

I want to make sure someone doesn't put

 

i.  Confusion and lack of knowledge

ii.  Confusion and lack of knowledge

iii.  Illiquidity

iv.  Index smoothing

v.  Pricing issues

 

for example
