Yes it did actually work... But VioneT was bright enough to remind me of the case sensitivity, which I totally missed in that one. You were right to assums I just wanted to include a value in another prompt, and by doing so, simply combine prompts before they are sent to the output. I'm not sure, but I think that way it'll be easier to manage the weight of certain inputs. So, if I'm correct (like I did in the gen, and as far as my brain lets me figure things out for itself), if I embed a certain input into all options of a different dropdown, with [input.Rtype], I could take that one out of the imageOptions prompts list, right... or else it will be double? By doing that I hope to create a more "workable" promptline for the AI to interpret. But I dunno... I'm just trying to make it make sense in my own brain, tbh.

https://perchance.org/ai-architecture-generator Don't mind the clutter in the styles... I'm trying to cook a soup from those! I added your suggested snippet into the "House" btype (building type)... where I tried to implement the selection of Rtype (roof type)... I hope I done it right, but I doubt it.

<thanks> Thank you so much! </thanks>

sorry... your suggestion still triggers an error on my end... yet I found an effective, yet code-heavier, solution to avoid errors... conditional prompting::

        Line-Art style
          if [input.Lighting] != "":
          prompt = [input.description], (line drawing:1.8), (no gradients:1.8), clean lines, no color, black and white, visible hatching, high contrast, high resolution, high detail, intricate details, 4k, wallpaper, concept art, pen on paper, [input:Lighting]
          else:
          prompt = [input.description], (line drawing:1.8), (no gradients:1.8), clean lines, no color, black and white, visible hatching, high contrast, high resolution, high detail, intricate details, 4k, wallpaper, concept art, pen on paper, 
          negative = [input.negative], low-quality, deformed, text, poorly drawn, 3D, color, gradients, greyscale, shading

Thanks so much, VioneT. I have tried the same as you just said... and it still kept giving me an error on the environment block... yet it wasn't consistent... Been trying to solve it for two whole days, yet the error kept popping back up. Now, after you gave this info, I noticed the error would only just appear when I reload the generator and the Environment option got set back to its empty default. So, all I had to do was set a default for environment. (or remember = true) Thank you nonetheless for your input! You underlined what I already thought would be most logical.

pester pester Yes, I agree... this should be resolved!
