Invalid Text Operation Error!

Please tell me how can I solve this error which thing need to change

It will be hard to help with just that error message. You need to show blocks and tell what are you trying to do.

Most probably this is the case, check your blocks


Please reply

Use Do it to debug your blocks

I can understand please explain where is error and how can I solve this

Your segment block is returning negative integer instead of positive value. Maybe your calculation for Segment block specifically the calculation in the parameter you are passing in the length socket

Its not, thats what the error is saying. length (End - Start) is -221500. Use do it and see what is being sent in response content by checking variables.
