The proc template runs and it says overwriting existing template/link :linechart stagragh linechart has been saved to sasuser.templat

The Marco the last part of code I rec a warning message
" the linechart statement named linechart will not be drawn because one or more of the required arguments were not supplied it tells me in blue 80k records were read for year 2020 ...I need help to determine missing arguments thanks again

dynamic year="&year;"; /* Pass the year to the template */

Do you need the semicolon in the quotes? I suspect that's an issue. You may not even need quotes if it's defined as numeric value.  EDIT: You do need the quotes though.

dynamic year="&year";

It didnt work rec same warning missing arguments the code I found in sas documents under how to create line chart statement ... the data I'm using looks like this
Day. Which is format Date9. Company formation $9. Total format best12. When I try the example code that pings the help folder it works

One strongly suspects something in your data set named companys. Either their are missing values or the variable names are spelled differently than you used in the template.

I also would suggest running your Sgrender code without any macro variables.

Got it had date instead of day
