IFS #VALUE error

[rosswelsh96]

I have two dropdown lists that when selected should produce a specifc value. The first half of the IFS formula works but the second half give the #VALUE error. Can anyone advise on what I have done wrong with this formula. 

=IFS(SEARCH("HIGH",AB28)*AND(SEARCH("Ground Beams/ Suspended in-situ Concrete Floor",AC28)),150,SEARCH("MEDIUM",AB28)*AND(SEARCH("Ground Beams/ Suspended in-situ Concrete Floor",AC28)),100)

@rosswelsh96 

=IF(ISNUMBER(SEARCH("HIGH",AB28))*ISNUMBER(SEARCH("Ground Beams/ Suspended in-situ Concrete Floor",AC28)),150,IF(ISNUMBER(SEARCH("MEDIUM",AB28))*ISNUMBER(SEARCH("Ground Beams/ Suspended in-situ Concrete Floor",AC28)),100))

The IF formula returns the expected result.

With IFS it would be:

=IFS(ISNUMBER(SEARCH("HIGH",AB28))*ISNUMBER(SEARCH("Ground Beams/ Suspended in-situ Concrete Floor",AC28)),

150,

ISNUMBER(SEARCH("MEDIUM",AB28))*ISNUMBER(SEARCH("Ground Beams/ Suspended in-situ Concrete Floor",AC28)),

100)
