Evaluating multiple If conditions in Robot framework

I am trying to evaluate below expression in Robot framework

Run Keyword If '${buttondisplayed}' == 'PASS' and '${ReturnedInfo}' == ' PASS', Some Keyword,

else if, '${buttondisplayed}' == 'PASS' and '${ReturnedInfo}' == 'FAIL', Some Keyword ,

else if, '${buttondisplayed}' == 'FAIL' and '${ReturnedInfo}' == 'PASS', Some Keyword,

else, Some Keyword

Where the value of both ${buttondisplayed} and ${ReturnedInfo} = FAIL.

Based on above condition , else part mentioned in the end should be executed however in Log output I am getting following result

Documentation:
Runs the given keyword with the given arguments, if condition is true. Start / End / Elapsed: 20170806 11:15:14.448 / 20170806 11:15:14.448 / 00:00:00.000

Could anyone please indicate what is wrong here in this expression ?
