Hello Glider 
I am sending this message since, I need some help. I would like to know how to use a math column for the stripe price ? I cannot see the column math in the price stripe field. Please see the screenshot with the detail of math.
Letting you know I am using a Column is user-specific in the calculation
Could you please advise ?
Regards,
The price column must be a Sheet column. You can not use Glide columns for this, for security reasons.
OK thanks for your answer @ThinhDinh
Do you know if I could have a Column “is user-specific” in Google sheets ?
No, user-specific columns are Glide columns as well.
OK thanks @ThinhDinh
Now you can use USC for Stripe price field, see my pics
But I still don’t understand why we can’t use a Math column, Template or a Rollup into Price filed yet?
Instead, we can choose a Boolean or Link, it doesn’t make sense!! 
Any help to fix it @mark or @david in order to improve how to buy with Stripe button?
Thanks in advance.
Saludos!
