Sequence has thrown an exception error message

Hi Friends,

I am new to UiPath. I completed the Lesson 2 Practice 2 - Guessing Game successfully.

While providing the input values multiple time I am getting the below error message.

Error

I thought there is some problem with my project so I downloaded the project from UiPath academy and ran the project. Still, I am getting the same error message. Can anyone tell me how can I resolve that error message.

Use Convert.Toint32 for the input which you are providing and check @BhaskarSharma

Thanks Sreekanth
