Hi Devendra,

Really appreciate you can create this great plugins and this plugin really useful in my project. No issue when I evaluate math calculation, but I found an issue when evaluate string expression.

In your description example : (LastName = 'Smith' OR LastName = 'Jones') AND FirstName = 'John' , so maybe I assume it seems the plugin should be also can evaluate string, but when I tried modify your sample demo and test it, an error occurred like screenshot below.

Can you also give me example how to use evaluate string text?

Please find sample demo that I had modified in attachment.

Really appreciate if you can give me clue how to fix this.

Thanks.

Additional notes :
I have requirement to evaluate dynamic expression that can consist of comparing amount and text (for example expense type), the result should be only true or false.
