Cannot use arithmetical operator in expression with value evaluate as number

[olivier.thomas.carto]

Hello! This is maybe a newby question but I am trying to make an horizontal scroll like the one in the AirBnb like template

I am trying to reproduce this expression Workflow:

But when I try to write it in my project or even in the template I have an issue with the/ operator. I cannot validate it.

Do you have an idea why I cannot rewrite the same expression ?

Thanks

You need to select the / and not type it manually. Also be sure that #current page width is a number

After item# current page width the expression evaluates to an item of the list wich is not a number, so you can’t divide it.
Possible solutions:

• enable parenthesis from the experimental features in the settings.
• calculate the number in an external group an reference it in the expression

Hi @Jici
The / is not in the list of options

Also the #current page seems to be evaluate as a number. So I don’t understand why I cannot use arithmetical operators

Hi @dorilama
In the expression item# current page widthseems to be a number (with or without the parenthesis)

You’re clicking on the wrong ‘more button’…

The last part of the expression inside the parenthesis evaluates to a number, so you need to click the ‘More’ button inside the parenthesis to continue using it as a number.

The expression overall evaluates to an Item from the RG (a Category, not a number) so clicking the ‘More’ button outside the parenthesis will not give you numerical operations:

This is what you will see if you click on the correct ‘More’ button (i.e. the one that evaluates to a number):
