Extract Data From Table Based on Multiple Criteria within ranges - arrays

Question

I have a problem that I would like someone to help me with.
I need to cross data from a table, the table is the following below:
Literally I want to put in the "Yellow" line the amount I want, it can be any one from 0 to 3000. If in "Yellow" put for example 190, which is up to 200, then it will select column F. If you put 1000, then will already select column H.
Then I need to cross data with the lines, which will be up to x m2. That is, if in the line where it says "Green" select for example 0.3. Then it will select line 15. The Result of the 2 questions would be 1000 in this example.
However, I've already made a few attempts, and there I arrived at a formula killer:
=IFS(AND($E$20<=$F$14;$E$21<=$E$15);$F$15;AND($E$20<=$F$14;$E$21<=$E$16);$F$16;AND($E$20<=$F$14;$E$21<=$E$17);$F$17;AND($E$20<=$F$14;$E$21<=$E$18);$F$18;AND($E$20<=$G$14;$E$21<=$E$15);$G$15)
And this formula continues until the end. It's effective, it does its job, but in addition to being huge, it also makes it difficult to edit one day. I would like to try to improve it.
Any idea?
I apologize to everyone who was confused by my earlier attempt to explain my problem. Thank you all.

Answer 1

Per my understanding you are looking for two match criteria. For yellow criteria you look for exact match and for green criteria, the exact match or the next upper value.
You can use INDEX/XMATCH for that as follow using LET function in cell J3:
=LET(rng, B2:G5, upper, 1*TEXTAFTER(TEXTBEFORE(A2:A5, " m2"), " ", -1),
INDEX(rng, XMATCH(J2, upper, 1), XMATCH(J1, B1:G1))
)
or without LET function:
=INDEX(B2:G5, XMATCH(J2, 1*TEXTAFTER(TEXTBEFORE(A2:A5, " m2"), " ", -1), 1),
XMATCH(J1, B1:G1))
Note: The above approach doesn't require a helper column with the upper values, if such information is provided like in the updated version of the question (column E), then use the corresponding range instead.
Here is the output:
It assumes there is a space between m2 and the number in the green column. You need to standardize it in your input. For example the last green row doesn't have a space. If that is not the case you need to cleanup it first, via SUBSTITUTE function for example or manually it seems to be a typo.
The name upper contains the number associated to m2 in the green column using TEXTBEFORE and TEXTAFTER. The first XMATCH uses the third input argument (1) to ensure if the value doesn't exist, then it finds the next upper value. The second XMATCH look for an exact match for the yellow column.
This is a well known use case: Two dimensional lookup or two way lookup. For example you can check: INDEX XMATCH XMATCH to perform 2-dimentional lookup and just to adapt it to your specific case. You can also use XLOOKUP function for similar situations.

Answer 2

I'm trying to do it the way you showed me. However, I don't use excel and therefore I don't have this "LET" formula.
I had to improvise.
Followed this way:
I made a new column with the intended values.
All these values would be approximate, for example, if I put 150 in quantity and say that they are 5m2, it would give me the result of 1400. This is because it is below 200 units and below 5m2. Another example, if you put 499 units and put 13m2, then the result would be 360,
Currently, with this formula, I have already achieved approximations. However, the values are not matching up and when I pass 1500 units then it gives me this error: The value of Parameter 2 of the INDEX function, 5, is out of range.
Have a good year David.
