Hi Pavel!
Did you by any chance add extra HTML codes to your project?

Please give me more info!
Thank you!

I wanted to change the heading in normal text box, but going into the "format cells" goes an error and the program closes. It is not with all text blocks, and with some, helps deleting and creating a new one of the same block, but it is not out of the situation. About html I do not understand! As I can throw you a copy of your project for you all to see? Or can get access to my computer what would you remotely managed to solve the problem!

Ok, thank you for the info.
Could you please kindly create a new project and repeat the same procedure you did in the previous (before you receive the error message) ? After, please let me know if the same thing happens. If it doesn't happen, it means that there is something wrong with your project therefore you can send it to me at ''file@answers.websitex5.com''. Please add my name + your post number (30471) in the email object and I will then be able to test it myself.
Thank you!
