Indeed it worked! However it makes the parameter to be uppercase in the URL. Could it cause an issue somehow?
Initially, I tried to convert the current cell’s portfolio’s display to lowercase in conditional formatting such asCurrent cell's Portfolio's Display:lowecase but I couldn’t, the :lowercase option did not show up. This is why I tried to change the parameter to lowercase first and then converting it to uppercase in the conditional formatting with Get asset from page URL:uppercasebefore evaluation with the Current cell's Portfolio's Display but I don’t understand why it didn’t work.
