I have two tables converting from matrixes:

```
Table 1:
Column1     Column2    Value
1          A          3
1          B          4
1          C          5
2          A          1
2          B          2
2          C          3

Table 2
Column1     Column2    Value
1          C         5
2          C          1
2          B          2

```

And i want multiply value from this two tables, if they have the same criteria. For example:

```
If [Table1[Column1] == Table2[Column1] AND Table1[Column2]==Table2[Column2]
THEN Table1[Value] <- Table1[Value]*Table2[Value]

```

Expected output:

```
Table 1:
Column1     Column2    Value
1          A          3
1          B          4
1          C          5*5 - from table 2
2          A          1
2          B          2*2 from table 2
2          C          3*1 - from table 2

```

I tried for few days create script, but i have a lot of of issues.
