help with if and round/mround functions

hello team
i am new on this thread and in excel i am a complete novice and trying to learn . My requirememnt is below
Amount of Vitamins and Minerals < 1% 0
Amount of Vitamins and Minerals ≥ 1% to < 2% all cases 2%
Amount of Vitamins and Minerals ≥ 2% to ≤ 10% round to nearest multiple of 2 %
Amount of Vitamins and Minerals >10% to ≤ 50% round to nearest multiple of 5 %
Amount of Vitamins and Minerals >50% round to nearest multiple of 10%


i tried
=IF(M22<50.01,0),IF(0.01<=M22<0.02,0.02),IF(0.02<=M22<=0.1,MROUND(M22,0.02),IF(0.1<M22<=0.5,MROUND(M22,0.05),IF(M22>0.5,MROUND(M22,0.01))))

but somehow i am getting value error

can someone tell me where i am going wrong

basically what i am trying to do is automatically calculating the daily recommended values in the food we eat based on what the GVT thinks we need.the values i added on the prior mail is where i failed to do the calculation. There is no sensitive infoirmation so far
After i figure out the Canada part then i will move to the US section of it
again the requirements for where it says #value is

Amount of Vitamins and Minerals < 1% 0
Amount of Vitamins and Minerals ≥ 1% to < 2% all cases 2%
Amount of Vitamins and Minerals ≥ 2% to ≤ 10% round to nearest multiple of 2 %
Amount of Vitamins and Minerals >10% to ≤ 50% round to nearest multiple of 5 %
Amount of Vitamins and Minerals >50% round to nearest multiple of 10%

as you see on the first 2 requirements no rounding necessary
M22 is where my value is ( this might not match with excel file attached as i had copied it before sending earlier.

Thanks Jete Mc : minor correction and this works like a charm

=IF(K22<0.01,0,IF(AND(0.01<=K22,K22<0.02),0.02,IF(AND(0.02<=K22,K22<=0.1),MROUND(K22,0.02),IF(AND(0.1<K22,K22<=0.5),MROUND(K22,0.05),IF(K22>0.5,MROUND(K22,0.01))))))

dont see when to comment this as solved
