In Studio Web, I am practicing automating the “[Find Unicorn Name](https://www.rpasamples.com/findunicornname)” exercise as part of the Agentic Automation Associate certification path. I have tried to set the month value for the ‘What month were you born?’ dropdown. I was able to see all available month values in the Studio Web Select Item activity. However, when I try to pass a variable or argument to select the month, I get an error and value set as ‘null’ (see below screenshots). If I type the string directly, it works. How can I fix this?

> Dear @martin_sola_ferreiro, This seems to be bug in UiPath select item activity. The solution I am gonna propose is an hard way. Step1: Open you studio web project in UiPath desktop studio. Step2: Close studio web & try to edit the code in desktop studio. Just add simple log message activity. Step3: Open the project folder…

Please let me know if you have any other queries.  
Else kindly mark it as solution.
