nested ifs with multiple sumifs based on changing criteria

I am having trouble with this formula and would like to know if I am even building it in the correct order or how i can change it to get the desired result. Getting formula missing an opening or closing parenthesis error:

=IF(BH2="PPD TO FSC",SUMIFS('ALL BIDS'!R:R,'ALL BIDS'!D:D,BV2,'ALL BIDS'!E:E,I2,'ALL BIDS'!W:W,'DC TOOL'!U2,'ALL BIDS'!G:G,'DC TOOL'!V2,'ALL BIDS'!H:H,'DC TOOL'!M2),SUMIFS(FREIGHT!Z:Z,FREIGHT!Q:Q,'DC TOOL'!F2,FREIGHT!M:M,H2,FREIGHT!O:O,"PPD",FREIGHT!AA:AA,GRIDS!$U$3),IF(BH2="PPD TO GDC",SUMIFS('ALL BIDS'!R:R,'ALL BIDS'!D:D,F2,'ALL BIDS'!E:E,I2,'ALL BIDS'!W:W,'DC TOOL'!U2,'ALL BIDS'!G:G,'DC TOOL'!V2,'ALL BIDS'!H:H,'DC TOOL'!M2),SUMIFS(FREIGHT!Z:Z,FREIGHT!Q:Q,'DC TOOL'!F2,FREIGHT!M:M,H2,FREIGHT!O:O,"PPD",FREIGHT!AA:AA,GRIDS!$U$3))
