Hi All,

I have a simple unit conversion formulas that I use on my HP17BII /HP17BII+ and decided to consolodate 3 of these into a single menu using the S() function. I have 2 nested IF(S(nnn)... functions, with a total of 3 equations:

LENGTH: IF(S(MM) OR S(INCH): MM * 0.03937007874 – IN: IF(S(M) OR S(FEET):M * 3.280839895 – FT : KM * 1.609344 - MILE))

The equation on the left most runs instantiously (mm-inch), while the two on the right iterate though the solution for some reason! On the 17BII, you get calculating, and the 17BII+ shows the min max iterations.

Run as stand-alone equations, they run instantly. Any ideas on how to fix this behavior?
