I currently had a browser enabled InfoPath form which would open from SharePoint. I recently made changes in SharePoint Designer (specifics here, it's the accepted answer: Simple way to color code a column in a document library?) and now my InfoPath form will still open in a browser and can be saved, but if I want to modify it, it wont let me open the form in a browser. It has to be opened in the client application. Any help/suggestions as to how I can modify it through the browser?
Wouldn't you just want to use rules within InfoPath to handle that? You can create display rules based on the value of fields.
just check what is the extension of the form- .xsn or .xml?
fyi .xml will open in browser and .xsn will open in client
