Need help nesting SUM and AND in multiple IFs formula!

Hello, community. I'm seeking help to solve the following formula and would greatly appreciate any and all solutions and suggestions.

Need to solve:

=IF(SUM(G60:G79)<2,"DAY",IF(AND(SUM(G60:G79)>1,SUM(G60:G79)<6,="WEEK",IF(SUM(G60:G79)>5,"MONTH")),0))

First and third IFs function properly individually:

=IF(SUM(G60:G79)<2,"DAY",0)

=IF(SUM(G60:G79)>5,"MONTH",0)

Second IF returns FALSE regardless of tweaking:

=IF(AND(SUM(G60:G79)>1,SUM(G60:G79)<6,"WEEK"),0)

Cells G60 thru G79 contain varying quantities of days. The purpose of this intended formula is to determine whether the rounded up sum of cells G60 thru G79 equals a 1 or "DAY", 5 or "WEEK", or 6+ or "MONTH". As shown above, I'm able to successfully produce the first and third IFs as standalone formulas, so I suspect that the FALSE result stems from an error in the second IF containing the nested AND. As a note, I'm aware of the IFS function and am experiencing similar if not the same challenge as my attempted IF formula. I'm also aware of the SWITCH alternative to IFS/multiple IFs, but have only seen it suggested as a solution to simplifying multiple entries from a list or table of text or number values and not from a SUM.

That's all the best information I can think of to include, but let me know if any more is needed to solve my issue.

Thanks in advance!
