Please help me solve the unrecognized errors line 18-29

prompt = ["input wet or dry:","What value do you want to find [time/thickness]:", "input the temperature in Kelvin:","enter index"];
dlgtitle = 'Values';
dims = [1 35];
answer = inputdlg(prompt,dlgtitle,dims);
global index %%creates popup display
global T
global kB
global X
str = string(answer{1}); %%creates string
str2 = string(answer{2});
T = str2num(answer{3});
index = string(answer{4}); %%creates index
kB = 8.617*10^-5; %%constant value kB
if str == 'wet' && str2 == "thickness" %%time and thickness
    fprintf ("you want to find wet time!")
    wettime(X)
elseif str == "wet" && str2 == "time"
    fprintf ("you want to find wet thick!")
    wetthick(X)
elseif str == "dry" && str2 == "thickness"
    fprintf ("you want to find dry time!")
    drytime(X)
elseif str == "dry" && str2 == "time"
    fprintf ("you want to find dry thick!")
    drythick(X)
else
    fprintf ("input not understood try again")
end

To compare two strings use strcmp. Read about it.

prompt = ["input wet or dry:","What value do you want to find [time/thickness]:", "input the temperature in Kelvin:","enter index"];
dlgtitle = 'Values';
dims = [1 35];
answer = inputdlg(prompt,dlgtitle,dims);
global index %%creates popup display
global T
global kB
global X
str = string(answer{1}); %%creates string
str2 = string(answer{2});
T = str2num(answer{3});
index = string(answer{4}); %%creates index
kB = 8.617*10^-5; %%constant value kB
if strcmp(str,'wet') && strcmp(str2,"thickness") %%time and thickness
    fprintf ("you want to find wet time!")
    wettime(X)
elseif strcmp(str,"wet") && strcmp(str2,"time")
    fprintf ("you want to find wet thick!")
    wetthick(X)
elseif strcmp(str,"dry") && strcmp(str2,"thickness")
    fprintf ("you want to find dry time!")
    drytime(X)
elseif strcmp(str,"dry") && strcmp(str2,"time")
    fprintf ("you want to find dry thick!")
    drythick(X)
else
    fprintf ("input not understood try again")
end
