If text mathces column 1 range, display value in column 2 cell

Please find the worksheet attached. Areas of interest are highlighted in BRIGHT ORANGE.

'GeneralInformation'!I39:I98 is the range with the option of DME or O&M

Part 1: If range 'GeneralInformation'!I39:I98 is all "DME" and some blank, then I want 'DME'!H28 to contain the full value of cell 'GeneralInformation'!I24

Part2: If the range 'GeneralInformation'!I39:I98 contains "DME" AND "O&M" and blank, then I want 'DME'!H28 to contain .5(half) the value of cell 'GeneralInformation'!I24'. The other .5(half) will then display in 'O&M'!H28.

Likewise, If range 'GeneralInformation'!I39:I98 is all "O&M" and some blank, then I want 'O&M'!H28 to contain the full value of cell 'GeneralInformation'!I24. Then follows the logic of Part 2 above.
