VBA Trouble with Hiding Rows

Good Morning!

I have been stumped on this problem for awhile and no matter what I use - SOMETHING goes wrong.

What I am doing is creating an invoice (for various users) to fill out. There are 9 different sections. One section has five subsections, another has four subsections, six sections have one subsection, and the last section does not have a subsection.

Once the client receives the invoice from a user - they will open two additional sheets - each that looks like the invoice (but not exactly since each sheet performs a breakdown of cost and differences).

The purpose of this particular VBA is to hide all the unused rows (and/or affiliated rows) when the user has completed filling out the invoice form. I have tried different codings - but again - SOMETHING keeps going wrong.

The lastest coding that I have is for the first section (with subsections):

Range (Cells) Z = Total of the line (which is Qty.*Rate)

'First subsection
If Range("Z25").Value = 0 Then Rows("25:26").Hidden = True
If Range("Z27").Value = 0 Then Rows("27:28").Hidden = True
If Range("Z29").Value = 0 Then Rows("29:30").Hidden = True
If Range("Z31").Value = 0 Then Rows("31:32").Hidden = True
If Rows("25:32").Hidden = True Then Rows("24").Hidden = True 'takes out header

'Second subsection
If Range("Z35").Value = 0 Then Rows("35:36").Hidden = True
If Range("Z37").Value = 0 Then Rows("37:38").Hidden = True
If Range("Z39").Value = 0 Then Rows("39:40").Hidden = True
If Range("Z41").Value = 0 Then Rows("41:42").Hidden = True
If Rows("35:42").Hidden = True Then Rows("33:34").Hidden = True 'takes out header and line above

'Third subsection
If Range("Z45").Value = 0 Then Rows("45:46").Hidden = True
If Range("Z47").Value = 0 Then Rows("47:48").Hidden = True
If Range("Z49").Value = 0 Then Rows("49:50").Hidden = True
If Range("Z51").Value = 0 Then Rows("51:52").Hidden = True
If Rows("45:52").Hidden = True Then Rows("43:44").Hidden = True ' takes out header & line above

'Fourth subsection
If Range("Z55").Value = 0 Then Rows("55:56").Hidden = True
If Range("Z57").Value = 0 Then Rows("57:58").Hidden = True
If Range("Z59").Value = 0 Then Rows("59:60").Hidden = True
If Range("Z61").Value = 0 Then Rows("61:62").Hidden = True
If Range("Z63").Value = 0 Then Rows("63:64").Hidden = True
If Range("Z65").Value = 0 Then Rows("65:66").Hidden = True
If Range("Z67").Value = 0 Then Rows("67:68").Hidden = True
If Range("Z69").Value = 0 Then Rows("69:70").Hidden = True
If Range("Z71").Value = 0 Then Rows("71:72").Hidden = True
If Range("Z73").Value = 0 Then Rows("73:74").Hidden = True
If Range("Z75").Value = 0 Then Rows("75:76").Hidden = True
If Range("Z77").Value = 0 Then Rows("77:78").Hidden = True
If Range("Z79").Value = 0 Then Rows("79:80").Hidden = True
If Range("Z81").Value = 0 Then Rows("81:82").Hidden = True
If Range("Z83").Value = 0 Then Rows("83:84").Hidden = True
If Range("Z85").Value = 0 Then Rows("85:86").Hidden = True
If Range("Z87").Value = 0 Then Rows("87:88").Hidden = True
If Range("Z89").Value = 0 Then Rows("89:90").Hidden = True
If Rows("55:90").Hidden = True Then Rows("53:54").Hidden = True ' takes out header & line above

'Fifth subsection
If Range("Z93").Value = 0 Then Rows("93:94").Hidden = True
If Range("Z95").Value = 0 Then Rows("95:96").Hidden = True
If Range("Z97").Value = 0 Then Rows("97:98").Hidden = True
If Range("Z99").Value = 0 Then Rows("99:100").Hidden = True
If Range("Z101").Value = 0 Then Rows("101:102").Hidden = True
If Range("Z103").Value = 0 Then Rows("103:104").Hidden = True
If Range("Z105").Value = 0 Then Rows("105:106").Hidden = True
If Rows("93:106").Hidden = True Then Rows("91:92").Hidden = True ' takes out header & line above

If Rows("24:106").Hidden = True Then Rows("22:113").Hidden = True 'for the whole section


The end result of this is that it hides the whole section - regardless if there are amounts or not UNLESS the very first row - Range("Z25") has a value > 0.

This is happening in all the sections.

What am I doing wrong?

Your help is VERY much appreciated!
