Which formula can use for identify the number and ignore the text

Hello,

Good Morning  !!!! : )

1) Formula is working fine (See the below images Sheet1,2,3). If you can see the below images that sheet3 have value "0" then this formulas is work but if in same shell (Sheet3) not data (Blank) ( Sheet11,12,13 ) than this formulas is not working. Same with Sheet2 shell.

It should work like that, If sheet2 have data and sheet3 no data (Blank) then sheet1 do calculation (8-Sheet2 shell) but if sheet2 have no data as well sheet3 no data then sheet1 should print only " A ".

Formula : 

=IF(Table19[@[01-Aug-19]]="Bank Holiday","Bank Holiday",IF(Table19[@[01-Aug-19]]="Holiday","Holiday",IF(Table19[@[01-Aug-19]]="Unpaid Leave","Unpaid Leave",IF(AND(IF(ISNUMBER(Table19[@[01-Aug-19]]),Table19[@[01-Aug-19]],TRIM(RIGHT(SUBSTITUTE(Table19[@[01-Aug-19]]," ",REPT(" ",LEN(Table19[@[01-Aug-19]]))),LEN(Table19[@[01-Aug-19]]))))>=0,IF(ISNUMBER(Table110[@[01-Aug-19]]),Table110[@[01-Aug-19]],TRIM(RIGHT(SUBSTITUTE(Table110[@[01-Aug-19]]," ",REPT(" ",LEN(Table110[@[01-Aug-19]]))),LEN(Table110[@[01-Aug-19]]))))>=0),"A ( "&8-IF(ISNUMBER(Table19[@[01-Aug-19]]),Table19[@[01-Aug-19]],TRIM(RIGHT(SUBSTITUTE(Table19[@[01-Aug-19]]," ",REPT(" ",LEN(Table19[@[01-Aug-19]]))),LEN(Table19[@[01-Aug-19]]))))-IF(ISNUMBER(Table110[@[01-Aug-19]]),Table110[@[01-Aug-19]],TRIM(RIGHT(SUBSTITUTE(Table110[@[01-Aug-19]]," ",REPT(" ",LEN(Table110[@[01-Aug-19]]))),LEN(Table110[@[01-Aug-19]]))))&"H )","A"))))

Please if you can help me.
