Thanks for the clear description and tip about the if clause parentheses 🙂  ... View more

Of course! Many thanks Dan for the swift response! ... View more

Thanks so much for taking the time to help here. The pure model builder solution has worked. I still have an itch as to why the other method didn't work, but I'll have to leave that unscratched for now! ... View more

Thanks, I tried using Add Field to create two new Float fields, populated one with the values from the original Long field, then tried to calculate percentages for the other and still got the same error message. The indentation is correct in the codeblock, it just looks slightly off because I had to paste those screenshots in two separate parts.  Running the codeblock to just return 'S' or 'a' also led to the same error. The ultimate goal is to make a chart map showing bar charts of how many species have been recorded in each 10km square over a region, for a variety of taxon groups, e.g. birds, plants, butterflies, etc. But I want the axes to be broadly comparable, and there a wildly different numbers of species in each taxon group in the region, e.g. 100s of plants but only 30 butterflies. So I want to show in each square, the percentage of all species in the region that have been recorded in that square, for each taxon group, like the table below but with many more taxon group columns: 10km square Plant_Species Plant_Species_% A 1245 32.38 B 515 13.39 C 1112 28.92 D 973 25.31   I just made this dummy table to try to figure out the calculate percentage part, but am falling down even at this first step!  How would I incorporate the results of a Summary Statistics into the field calculator? Is there a way to make the output from Summary Statistics into an inline variable in model builder?   ... View more

Sorry, what exactly do you mean by 'scale and precision for the field properties'? I can't see any options for those when creating a new field in Fields View or in Field Calculator. The table is a dummy table as I try to figure this out to later put it in a model. It only has 4 rows, and the values of the column I am trying to calculate percentages for are: 1245 515 1112 973 I have just tried running the calculation from two float fields, and also inserting float(a) and float(S) into the final line of my codeblock. Still getting the same error message! Thanks for your help so far. ... View more

Hi, thanks for the reply. Sorry, I realised I posted the wrong screenshot for the expression section, I have edited now. It should be: 'Plant_Taxa_Percentage' is a Double field, 'Plant_Taxa_Recorded' is a Long field. So I am using the codeblock above to try to populate the Double field with percentage values derived from the Long field. I've tried using int( (a/s) * 100) and get the same error message. I have also tried creating two new Double fields, populating one with the values from the Long field, and then calculating percentage from that in the other Double field, so that it was a Double to Double calculation, but still got the same error message. I then wondered if the 'if len(list) == 0' bit of the code was causing issues, but I tried a previous accepted answer in the above thread that didn't have this component and still got the same error message...   ...

Great, thanks for the info Tom, happily in this case there is no need for the tags.   ... View more

Thanks Tom. What exactly do accessibility tags do? Am I losing anything by not having them? Didn't find a quick answer searching online. Interestingly, an interactive pdf with legend exported anyway, even with the 'PDF Layers Only' option selected, following Eugene's answer above.   ... View more

Thanks so much! I toggled 'Export georeference information' on the Export Map tab, but the 'PDF Layers and Features' option still wasn't appearing in the drop-down menu on the Export Layout tab, probably because of the 'Include Accessibility Tags' option was checked as Tom mentions below. However, this worked anyway, and even with selecting 'PDF Layers Only' it still exported a pdf with switchable layers and a legend. ... View more

Thank you for highlighting that! I misread the article. I have managed to export the map as an interactive pdf now, but it does not include any kind of legend. Is there any way to get a legend showing symbology on there?   ... View more

Many thanks Dan. I went for the Field Statistics to Table option, good to know about that! ... View more
