Multiple spreadsheet formula

[Yippy_Kiyey]

I have a spreadsheet that has 51 tabs. The first tab is a summary page of the other 50 tabs. The columns are identical but the rows are not although they contain similar information. I need to summarize this tabs by bringing or linking certain total onto the summary page. Right I do that by using the "=" sign, but it takes so much time and very prone to errors. I want a formula that will link all the totals that I can copy across or down. This will be more efficient and accurate. Below is an example.

Excel Workbook
	A	B	C	D	E
2	Tab1 - Summary
3		Funded	Jan	Feb	etc
4		101
5		102
6		103
7		Total Funded
8
9		Not Funded
10		101
11		102
12		103
13		Total Not Funded
14
15
16	Tab-Proj 101
17	Funded
18		Items	Jan	Feb	etc
19		AAA	10	11
20		BBB	10	11
21		CCC	10	11
22		Total Funded	30	33
23			(Link this total to line 6 Tab1 - Summary)
24
25	Not Funded
26		Items
27		AAA	5	8
28		BBB	5	5
29		CCC	3	3
30		Total not funded	13	16
31			(Link this total to line 12 Tab1 - Summary)
32
33	Tab-Proj 102
34	Funded
35		Items	Jan	Feb	etc
36		DDD
37		EEE
38		Total Funded
39			(Copy this total to line 7 Tab1 - Summary)
40	Not Funded
41		Items
42		DDD
43		EEE
44		Total not funded
45			(Copy this total to line 13 Tab1 - Summary)
Sheet1

Edit: Because I deleted some rows, the row number got messed up, ie, line 23 should read "link this total to line 4 tab 1 summary". Line 31 should say line 10 and so on and so forth.
