Hi…when I take print of sales invoice, the following error is showing:

Traceback (most recent call last):

Hi @Naveed1
If you are not using the standard format of sales invoice. Please find the format which is Standard = Yes and Custom Format = 1. Maybe the problem is with your html code in that format.

Hi @Safvan_Ph Hope you are fine. Actually in Standard Sales Invoice print and PDF both are OK. Actually I have created another print format Standard Modified, in this print format system throws an error.

Kindly suggest me how to fix it. Thanks

Hi @Naveed1
Kindly share both html and css code. then we can review the code.

Hi @Naveed1
Did you add any jinja code in the format?. Please check using Edit Format Button

No. I have not used jinja. When I click at edit format and then click show preview the following error shows
