Hi there,

I’m building a template where I need to show the ratios of the current and the previous year.

Calculating the ratios of the current year doesn’t give any problems, but I don’t know how to obtain the data of the previous year.

For instance this is the ratio of the liquidity of the current year:

`{% assign liquiditeitruim = (#3+#40+#41+#50+#51+#52+#53+#54+#55+#56+#57+#58+#490+#491)/(#42+#43+#44+#45+#46+#47+#48+#492+#493) %}`

But how do I calculate the ratio of the liquidity of the past year?

Thanks in advance!
