Help with ODK error- XForm is invalid...Encountered a problem with display condition node

Question

I am trying to use 'groups' in my survey which is new for me.  What I am trying to do is, for the question 'how many historic functions are there'... will be an integer answer between 1-3.  If the user enters 2, I'd like the appropriate number of fields to appear on the survey (for 2 it is 4 fields, for 3 it is 6 fields).  I added info to the relevant column and I think I am close but am running into the following error:

...XForm is invalid...Encountered a problem with display condition node [${HistoricalFunctionB}] at line:${HFunctionsGroup} ="1","2", Bad node...

I've included the spreadsheet, hopefully that will help! Thanks so much.

Your relevant conditions are formatted incorrectly.  Also since HFunctionsGroup is a group, there are no answers to it, I am guessing you want the relevant to reference ${HowManyHFunctions}

${HowManyHFunctions} ="1"  or ${HowManyHFunctions} ="2" or ...  That needs to be changed for:

I may also suggest  moving to using the selected function instead of "="  it is more robust especially when you use select_multiple:

selected(${HowManyHFunctions},'1') or selected(${HowManyHFunctions},'2')...

I would also suggest changing ${HowManyHFunctions} to a select_one question having the options 1,2 or 3. You currently don't have it constrained.  There may be other ways, but it is a straightfoward way to constrain the answers and have users know what to expect.

I think you will also need to flip the order

1 or 2  or 3

2 or 3
