I've been able to begin rendering my app from a fixed data base (birds with common name, scientific name, habitat, diet and misc fields). My initial test works. I still need to create the blocks where the variable will be the habitat field, of which there are three fields.
I've read and tried several approaches on displaying images in a google spreadsheet and nothing appears on the screen except an error message. I've tried editing the shared url with the following:
I have six columns:
genus (cannot get italics to generate either)
habitat (this is the variable - there are three)
image - 400 pixels high x 300 pixels wide
