Sorry but there are too many ways a sim can throw an error to guess just from a screenshot. You need to make your simulation public: [https://easyeda.com/forum/topic/How-to-make-a-Project-public-and-share-the-links-to-it-9f006513b84b412580910905b0281d20](https://easyeda.com/forum/topic/How-to-make-a-Project-public-and-share-the-links-to-it-9f006513b84b412580910905b0281d20)<br> <br> and share the url to it here. At least two of your problems are because one end of C1 is unconnected and V1 is completely unconnected. V1 also has an inappropriate voltage. The slider of the 2.2k pot is unconnected and the 741 power supply connections are incorrect.

It will help you to read the Simulation Tutorial (3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)
