how to evaluate one group of numbers by another group of numbers

[pantija]

Hello,
I am a self taught excel user and I bumped into a problem which after many tries I can't solve and I am not even sure how to approach it. In my work I have to manually input in excel on daily basis about 150 numbers in a single column and there are more than 50 columns like that with different numbers. For every column possible values are different and there are from 10 to 70 different number values for every single column. As this is manually done, typing errors can occur and I was looking for automatic check up of this. I tried with different variations of formulas to make a table in column which would contain all possible values for that column but I couldn't make it work.
eg. in column A1:A70 are numbers 1,01, 1,25, 1,5, 2, 10,... every number is different and only this numbers are correct possibilities for my manual input in this column. My manual input is in cells A100:A250 and I will be writing only set of numbers from A1:A70. I am searching for formula which will check all my manual input in cells A100:A250 and notify me if I used a value which is not in the list A1:A70.
Only limiting factor is that cells for check up must be in this column.
If You can help me with this issue I would really appreciate it.

something like:

if(isnumber(match(a100,$a$1:$a$70)),"On list","Not on list")

...copied for relevant data entry cells. you could also consider using something like the above in a conditional format or data validation formula to highlight / prevent erroneous entries.

yeeeeeeeey it works
I just added 0 for match type and for true and false value 0 and 1 so with additional counter I only have to check one cell to see if everything is errorless.
Thank You PaddyD!
