Responsive/sizeMapping returning wrong sizes

[ozeone]

Hello & thanks for an awesome script.
I am trying to set up a responsive pushdown panorama banner using 4 different sizes (3 breakpoints).
Banner load fine but the actual size mapping seems to be lost, all banners seem to load random no matter window size :/

I don't know what i am doing wrong here, according to all posts i find about this its the correct markup (or i have missed something vital?)

Best regards

Martin

The line items

In your ad tag, you should specify the data-size-mapping attribute not data-dimensions. With data-dimensions, it will randomly pick a creative size depending on your line items settings.

@omelsoft I have updated the pen and banners load, but its still the same result (mobile showing random no matter browser size), can you see what i am doing wrong?
I ma using both data-dimensions and data-size-mapping with the same values, is this the way to do it?

Feel free to update/fork pen ;) And thanks for helpinig

just got this to work i think, misunderstood the use data-size-mapping from start :/
I changed data-size-mapping to be the name of the size mapping (makes sense) and everything started working :)
