Not able to select item in drop down menu

[susheel.perugu (Susheel P)]

i am trying to use ‘select element’ activity to select an item from a drop down menu.
this dropdown menu is within a table. each row has dropdown menu to select item.

however this activity is throwing an error.
stating : cannot select item. it was not found among existing items.

i tried by clicking dropdown menu before selecting element. but not getting expected result.

can you help me in this regard.

Thanks a lot !

best regards,
Susheel
