SimpleSearch-1.5.2

Hello all I am a relative newbee and am having trouble with SimpleSearch in Revo-2.2.1-pl
I am getting these error messages when I employ the search add-on
"!SimpleSearchForm?"
" !SimpleSearch"

Notice: Undefined offset: 1 in core\components\simplesearch\model\simplesearch\driver\simplesearchdriver.class.php on line 117

Notice: Undefined offset: 21 in core\components\simplesearch\model\simplesearch\driver\simplesearchdriver.class.php on line 128

Does anyone know what the solution is?
Thanks
